Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels.

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:4429 advisory.

    The Container Network Interface (CNI) project consists of a specification and libraries for writing plug-     ins for configuring network interfaces in Linux containers, along with a number of supported plug-ins. CNI     concerns itself only with network connectivity of containers and removing allocated resources when the     container is deleted.

    Security Fix(es):

    * golang: crypto/tls: Timing Side Channel attack in RSA based TLS key exchanges. (CVE-2023-45287)

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-2988 advisory.

  - The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an     X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS     server to cause a TLS client to panic. (CVE-2021-34558)

  - The html/template package does not apply the proper rules for handling occurrences of <script, <!--,     and </script within JS literals in <script> contexts. This may cause the template parser to improperly     consider script contexts to be terminated early, causing actions to be improperly escaped. This could be     leveraged to perform an XSS attack. (CVE-2023-39319)

  - BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and     repeatable manner. A malicious BuildKit client or frontend could craft a request that could lead to     BuildKit daemon crashing with a panic. The issue has been fixed in v0.12.5. As a workaround, avoid using     BuildKit frontends from untrusted sources. (CVE-2024-23650)

  - Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time     verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <=     8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in     circulation with keys larger than this, and all three appear to be test certificates that are not actively     deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so     causing breakage here in the interests of increasing the default safety of users of crypto/tls seems     reasonable. (CVE-2023-29409)

  - The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other     products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the     extension negotiation message), and a client and server may consequently end up with a connection for     which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because     the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and     mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of     ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and     (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API     before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80,     AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0,     Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15,     SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH     through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang     XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd     through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and     LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3,     Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server     before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the     mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh     crate before 0.40.2 for Rust. (CVE-2023-48795)

  - Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA     blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective.
    In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn     could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant     time RSA implementation, which we do not believe exhibits any timing side channels. (CVE-2023-45287)

  - In Go before 1.15.13 and 1.16.x before 1.16.5, there can be a panic for a large exponent to the     math/big.Rat SetString or UnmarshalText method. (CVE-2021-33198)

  - QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake     messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now     consistently reject messages larger than 65KiB in size. (CVE-2023-39322)

  - Processing an incomplete post-handshake message for a QUIC connection can cause a panic. (CVE-2023-39321)

  - A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response     body to read many more bytes from the network than are in the body. A malicious HTTP client can further     exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a     handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which     permit including additional metadata in a request or response body sent using the chunked encoding. The     net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large     metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real     body to encoded bytes grows too small. (CVE-2023-39326)

  - urllib3 is a user-friendly HTTP client library for Python. urllib3 previously wouldn't remove the HTTP     request body when an HTTP redirect response using status 301, 302, or 303 after the request had its method     changed from one that could accept a request body (like `POST`) to `GET` as is required by HTTP RFCs.
    Although this behavior is not specified in the section for redirects, it can be inferred by piecing     together information from different sections and we have observed the behavior in other major HTTP client     implementations like curl and web browsers. Because the vulnerability requires a previously trusted     service to become compromised in order to have an impact on confidentiality we believe the exploitability     of this vulnerability is low. Additionally, many users aren't putting sensitive data in HTTP request     bodies, if this is the case then this vulnerability isn't exploitable. Both of the following conditions     must be true to be affected by this vulnerability: 1. Using urllib3 and submitting sensitive information     in the HTTP request body (such as form data or JSON) and 2. The origin service is compromised and starts     redirecting using 301, 302, or 303 to a malicious peer or the redirected-to service becomes compromised.
    This issue has been addressed in versions 1.26.18 and 2.0.7 and users are advised to update to resolve     this issue. Users unable to update should disable redirects for services that aren't expecting to respond     with redirects with `redirects=False` and disable automatic redirects with `redirects=False` and handle     301, 302, and 303 redirects manually by stripping the HTTP request body. (CVE-2023-45803)

  - Requests forwarded by ReverseProxy include the raw query parameters from the inbound request, including     unparsable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy     forwards a parameter with an unparsable value. After fix, ReverseProxy sanitizes the query parameters in     the forwarded query when the outbound request's Form field is set after the ReverseProxy. Director     function returns, indicating that the proxy has parsed the query parameters. Proxies which do not parse     query parameters continue to forward the original query parameters unchanged. (CVE-2022-2880)

  - The html/template package does not properly handle HTML-like  comment tokens, nor hashbang #! comment     tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of     <script> contexts, causing actions to be improperly escaped. This may be leveraged to perform an XSS     attack. (CVE-2023-39318)

  - urllib3 before 1.24.2 does not remove the authorization HTTP header when following a cross-origin redirect     (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the     authorization header to be exposed to unintended hosts or transmitted in cleartext. NOTE: this issue     exists because of an incomplete fix for CVE-2018-20060 (which was case-sensitive). (CVE-2018-25091)

  - Reader.Read does not set a limit on the maximum size of file headers. A maliciously crafted archive could     cause Read to allocate unbounded amounts of memory, potentially causing resource exhaustion or panics.
    After fix, Reader.Read limits the maximum size of header blocks to 1 MiB. (CVE-2022-2879)

  - Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion     or denial of service. The parsed regexp representation is linear in the size of the input, but in some     cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger     amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular     expressions whose representation would use more space than that are rejected. Normal use of regular     expressions is unaffected. (CVE-2022-41715)

The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:7201 advisory.

  - A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive     server resource consumption. While the total number of requests is bounded by the     http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create     a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound     the number of simultaneously executing handler goroutines to the stream concurrency limit     (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client     has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows     too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2     for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per     HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the     Server.MaxConcurrentStreams setting and the ConfigureServer function. (CVE-2023-39325)

  - A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response     body to read many more bytes from the network than are in the body. A malicious HTTP client can further     exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a     handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which     permit including additional metadata in a request or response body sent using the chunked encoding. The     net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large     metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real     body to encoded bytes grows too small. (CVE-2023-39326)

  - Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA     blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective.
    In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn     could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant     time RSA implementation, which we do not believe exhibits any timing side channels. (CVE-2023-45287)

  - The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other     products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the     extension negotiation message), and a client and server may consequently end up with a connection for     which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because     the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and     mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of     ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and     (if CBC is used) the -etm@openssh.com MAC algorithms.

  - runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In     runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned     container process (from runc exec) to have a working directory in the host filesystem namespace, allowing     for a container escape by giving access to the host filesystem (attack 2). The same attack could be used     by a malicious image to allow a container process to gain access to the host filesystem through runc run     (attack 1). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries,     allowing for complete container escapes (attack 3a and attack 3b). runc 1.1.12 includes patches for     this issue.
