ELSA-2024-2180 advisory.

  - Uncontrolled recursion in Glob in io/fs before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a
    panic due to stack exhaustion via a path which contains a large number of path separators.
    (CVE-2022-30630)

  - Uncontrolled recursion in Glob in path/filepath before Go 1.17.12 and Go 1.18.4 allows an attacker to
    cause a panic due to stack exhaustion via a path containing a large number of path separators.
    (CVE-2022-30632)

  - 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)

  - Uncontrolled recursion in Reader.Read in compress/gzip before Go 1.17.12 and Go 1.18.4 allows an attacker
    to cause a panic due to stack exhaustion via an archive containing a large number of concatenated 0-length
    compressed files. (CVE-2022-30631)

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