Alpine: multiple libgit2 packages: security update to 1.5.1-r0

medium Tenable Self-Hosted Container Security Plugin ID 405197

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - libgit2 is a cross-platform, linkable library implementation of Git. When using an SSH remote with the
 optional libssh2 backend, libgit2 does not perform certificate checking by default. Prior versions of
 libgit2 require the caller to set the `certificate_check` field of libgit2's `git_remote_callbacks`
 structure - if a certificate check callback is not set, libgit2 does not perform any certificate checking.
 This means that by default - without configuring a certificate check callback, clients will not perform
 validation on the server SSH keys and may be subject to a man-in-the-middle attack. Users are encouraged
 to upgrade to v1.4.5 or v1.5.1. Users unable to upgrade should ensure that all relevant certificates are
 manually checked. (CVE-2023-22742)
