		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">libgit2 is a portable, pure C implementation of the Git core methods provided as a re-entrant linkable library with a solid API, allowing you to write native speed custom Git applications in any language which supports C bindings.

Security Fix(es):

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)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for libgit2 is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS,openEuler-22.03-LTS-SP1,openEuler-22.03-LTS-SP2 and openEuler-22.03-LTS-SP3.

openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
