Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of runc installed on the remote host is prior to 1.1.3-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2DOCKER-2022-020 advisory.

2023-05-11: CVE-2022-1996 has changed status to NOT AFFECTED for this package and has been removed from this advisory.

A flaw was found in golang. The HTTP/1 client accepted invalid Transfer-Encoding headers indicating chunked encoding. This issue could allow request smuggling, but only if combined with an intermediate server that also improperly accepts the header as invalid. (CVE-2022-1705)

A flaw was found in the golang standard library, go/parser. When calling any Parse functions on the Go source code, which contains deeply nested types or declarations, a panic can occur due to stack exhaustion. This issue allows an attacker to impact system availability. (CVE-2022-1962)

A buffer overflow flaw was found in Golang's library encoding/pem. This flaw allows an attacker to use a large PEM input (more than 5 MB) ), causing a stack overflow in Decode, which leads to a loss of availability. (CVE-2022-24675)

A broken cryptographic algorithm flaw was found in golang.org/x/crypto/ssh. This issue causes a client to fail authentification with RSA keys to servers that reject signature algorithms based on SHA-2, enabling an attacker to crash the server, resulting in a loss of availability. (CVE-2022-27191)

A flaw was found in golang encoding/xml. When calling Decoder.Skip while parsing a deeply nested XML document, a panic can occur due to stack exhaustion and allows an attacker to impact system availability.
(CVE-2022-28131)

An integer overflow flaw was found in Golang's crypto/elliptic library. This flaw allows an attacker to use a crafted scaler input longer than 32 bytes, causing P256().ScalarMult or P256().ScalarBaseMult to panic, leading to a loss of availability. (CVE-2022-28327)

A flaw was found in the syscall.Faccessat function when calling a process by checking the group. This flaw allows an attacker to check the process group permissions rather than a member of the file's group, affecting system availability. (CVE-2022-29526)

Non-random values for ticket_age_add in session tickets in crypto/tls before Go 1.17.11 and Go 1.18.3 allow an attacker that can observe TLS handshakes to correlate successive connections by comparing ticket ages during session resumption. (CVE-2022-30629)

A flaw was found in the golang standard library, io/fs. Calling Glob on a path that contains a large number of path separators can cause a panic issue due to stack exhaustion. This could allow an attacker to impact availability. (CVE-2022-30630)

A flaw was found in golang. Calling the Reader.Read method on an archive that contains a large number of concatenated 0-length compressed files can cause a panic issue due to stack exhaustion. (CVE-2022-30631)

A flaw was found in golang. Calling Glob on a path that contains a large number of path separators can cause a panic issue due to stack exhaustion. This can cause an attacker to impact availability.
(CVE-2022-30632)

Uncontrolled recursion in Unmarshal in encoding/xml before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via unmarshalling an XML document into a Go struct which has a nested field that uses the any field tag. (CVE-2022-30633)

A flaw was found in golang. When calling Decoder.Decode on a message that contains deeply nested structures, a panic can occur due to stack exhaustion and allows an attacker to impact system availability. (CVE-2022-30635)

Improper exposure of client IP addresses in net/http before Go 1.17.12 and Go 1.18.4 can be triggered by calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the X-Forwarded-For header, which causes ReverseProxy to set the client IP as the value of the X-Forwarded-For header. (CVE-2022-32148)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
