CVE-2024-24577
Description
A flaw was found in libgit2, a cross-platform, linkable library implementation of Git. A specially crafted payload to git_index_add can cause heap corruption that could be leveraged for arbitrary code execution. The attacker must be able to trigger two consecutive calls to git_index_add with a filename that starts with a / character to exploit this vulnerability. To control the heap corruption, the attacker must be able to control the ctime field of the git_index_entry data structure.
Statement
Cargo in Red Hat Enterprise Linux 8 & 9 does use a bundled libgit2. However, cargo does not call git_index_add directly, and the only indirect call I can find is via git_reset, which does not involve any externally-provided paths. Therefore, Red Hat Enterprise Linux should be Not Affected by this CVE.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
