CVE-2024-24575Network attack vector

Application hang via crafted revision specification

Published Feb 6, 2024 · Updated Feb 13, 2025

Denial of service in libgit2 1.4.0 through 1.6.4 and 1.7.0 through 1.7.1 allows context-dependent attackers to hang calling applications. The parsing loop in src/libgit2/revparse.c lets a crafted revision specification force loop-condition reads from arbitrary memory and repeat indefinitely. Reachability requires a consuming application to pass attacker-influenced input to git_revparse_single; the established consequence is a hung calling process.
