CVE-2024-24575

Summary

CVE-2024-24575 is a vulnerability affecting the libgit2 library, which is used to build Git functionality into applications. The issue lies in the `git_revparse_single` function, where an infinite loop can be triggered through specially crafted inputs. This can lead to a Denial of Service (DoS) attack on the calling application. An attacker can also potentially extract arbitrary memory or cause memory leaks. The vulnerability is due to a parsing edge-case in the revparse function located in `src/libgit2/revparse.c`. Libgit2 versions before 1.4.0 are at risk, and users should upgrade to version 1.6.5 or 1.7.2 to mitigate this issue.
