Multiple NSS NIST curves were susceptible to a side-channel attack known as "Minerva". This attack could potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.

The version of AHV installed on the remote host is prior to 20220304.480. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.2024 advisory.

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

  - libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are     required in the case of a large token for which multiple buffer fills are needed. (CVE-2023-52425)

  - An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might     erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the     `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request     which used that callback. This flaw may surprise the application and cause it to misbehave and either send     off the wrong data or use memory after free or similar in the second transfer. The problem exists in the     logic for a reused handle when it is (expected to be) changed from a PUT to a POST. (CVE-2023-28322)

  - This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the     specific series of conditions are met. libcurl performs transfers. In its API, an application creates     easy handles that are the individual handles for single transfers. libcurl provides a function call that     duplicates en easy handle called     [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies     enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the     actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned     version of the handle would instead store the file name as `none` (using the four ASCII letters, no     quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from     would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in     the current directory of the program using libcurl. And if using the correct file format of course.
    (CVE-2023-38546)

  - CVE-2023-38546 is a cookie injection vulnerability in the curl_easy_duphandle(), a function in libcurl     that duplicates easy handles.  When duplicating an easy handle, if cookies are enabled, the duplicated     easy handle will not duplicate the cookies themselves, but would instead set the filename to none.'     Therefore, when the duplicated easy handle is subsequently used, if a source was not set for the cookies,     libcurl would attempt to load them from the file named none' on the disk.  This vulnerability is rated     low, as the various conditions required for exploitation are unlikely.  (CVE-2023-38546)

  - This flaw allows a malicious HTTP server to set super cookies in curl that are then passed back to more     origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get     sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in     curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a     cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though     `co.uk` is listed as a PSL domain. (CVE-2023-46218)

  - libmaxminddb before 1.4.3 has a heap-based buffer over-read in dump_entry_data_list in maxminddb.c.
    (CVE-2020-28241)

  - Multiple NSS NIST curves were susceptible to a side-channel attack known as Minerva. This attack could     potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.
    (CVE-2023-6135)

  - Use after free in tcpslice triggers AddressSanitizer, no other confirmed impact. (CVE-2021-41043)

  - 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.

  - Multiple NSS NIST curves were susceptible to a side-channel attack known as Minerva. This attack could     potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.
    (CVE-2023-6135)

  - Use after free in tcpslice triggers AddressSanitizer, no other confirmed impact. (CVE-2021-41043)

  - The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to     it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to     crash an application or overwrite a neighbouring variable. (CVE-2024-2961)

  - A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits     deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such     as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size     from 513 to 512 bits, exposing a potential timing side-channel. (CVE-2024-28834)

  - A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside     the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to     port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to     manipulate a running instance, potentially altering forwarders, allowing them to track all queries     forwarded by the local resolver, and, in some cases, disrupting resolving altogether. (CVE-2024-1488)

  - The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
    It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive     CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative     servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through     9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1     through 9.18.21-S1.

The remote host is affected by the vulnerability described in GLSA-202401-10 (Mozilla Firefox: Multiple Vulnerabilities)

  - When Firefox is configured to block storage of all cookies, it was still possible to store data in     localstorage by using an iframe with a source of 'about:blank'. This could have led to malicious websites     storing tracking data without permission. This vulnerability affects Firefox < 115. (CVE-2023-3482)

  - Memory safety bugs present in Firefox 115. Some of these bugs showed evidence of memory corruption and we     presume that with enough effort some of these could have been exploited to run arbitrary code. This     vulnerability affects Firefox < 116. (CVE-2023-4058)

  - Search queries in the default search engine could appear to have been the currently navigated URL if the     search query itself was a well formed URL. This could have led to a site spoofing another if it had been     maliciously set as the default search engine. This vulnerability affects Firefox < 117. (CVE-2023-4579)

  - Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a     remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security     severity: Critical) (CVE-2023-4863)

  - Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. Duplicate of     CVE-2023-4863. (CVE-2023-5129)

  - In canvas rendering, a compromised content process could have caused a surface to change unexpectedly,     leading to a memory leak of a privileged process. This memory leak could be used to effect a sandbox     escape if the correct data was leaked. This vulnerability affects Firefox < 118. (CVE-2023-5170)

  - A hashtable in the Ion Engine could have been mutated while there was a live interior reference, leading     to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 118.
    (CVE-2023-5172)

  - In a non-standard configuration of Firefox, an integer overflow could have occurred based on network     traffic (possibly under influence of a local unprivileged webpage), leading to an out-of-bounds write to     privileged process memory. *This bug only affects Firefox if a non-standard preference allowing non-HTTPS     Alternate Services (`network.http.altsvc.oe`) is enabled.* This vulnerability affects Firefox < 118.
    (CVE-2023-5173)

  - During process shutdown, it was possible that an `ImageBitmap` was created that would later be used after     being freed from a different codepath, leading to a potentially exploitable crash. This vulnerability     affects Firefox < 118. (CVE-2023-5175)

  - Using iterative requests an attacker was able to learn the size of an opaque response, as well as the     contents of a server-supplied Vary header. This vulnerability affects Firefox < 119. (CVE-2023-5722)

  - An attacker with temporary script access to a site could have set a cookie containing invalid characters     using `document.cookie` that could have led to unknown errors. This vulnerability affects Firefox < 119.
    (CVE-2023-5723)

  - The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to     protect prompts and permission dialogs from attacks that exploit human response time delays. If a     malicious page elicited user clicks in precise locations immediately before navigating to a site with a     certificate error and made the renderer extremely busy at the same time, it could create a gap between     when the error page was loaded and when the display actually refreshed. With the right timing the elicited     clicks could land in that gap and activate the button that overrides the certificate error for that site.
    This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12. (CVE-2023-34414)

  - When choosing a site-isolated process for a document loaded from a data: URL that was the result of a     redirect, Firefox would load that document in the same process as the site that issued the redirect. This     bypassed the site-isolation protections against Spectre-like attacks on sites that host an open     redirect. Firefox no longer follows HTTP redirects to data: URLs. This vulnerability affects Firefox <     114. (CVE-2023-34415)
