Alpine: multiple libgit2 packages: security update to 1.7.2-r0

critical Tenable Self-Hosted Container Security Plugin ID 408273

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid
 API, allowing to build Git functionality into your application. Using well-crafted inputs to
 `git_revparse_single` can cause the function to enter an infinite loop, potentially causing a Denial of
 Service attack in the calling application. The revparse function in `src/libgit2/revparse.c` uses a loop
 to parse the user-provided spec string. There is an edge-case during parsing that allows a bad actor to
 force the loop conditions to access arbitrary memory. Potentially, this could also leak memory if the
 extracted rev spec is reflected back to the attacker. As such, libgit2 versions before 1.4.0 are not
 affected. Users should upgrade to version 1.6.5 or 1.7.2. (CVE-2024-24575)

 - libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid
 API, allowing to build Git functionality into your application. Using well-crafted inputs to
 `git_index_add` can cause heap corruption that could be leveraged for arbitrary code execution. There is
 an issue in the `has_dir_name` function in `src/libgit2/index.c`, which frees an entry that should not be
 freed. The freed entry is later used and overwritten with potentially bad actor-controlled data leading to
 controlled heap corruption. Depending on the application that uses libgit2, this could lead to arbitrary
 code execution. This issue has been patched in version 1.6.5 and 1.7.2. (CVE-2024-24577)
