The maintainers of the Git resource code model management technique have produced updates to remediate two critical vulnerabilities that could be exploited by a malicious actor to reach distant code execution.
The flaws, tracked as CVE-2022-23521 and CVE-2022-41903, impacts the next variations of Git: v2.30.6, v2.31.5, v2.32.4, v2.33.5, v2.34.5, v2.35.5, v2.36.3, v2.37.4, v2.38.2, and v2.39..
Patched variations involve v2.30.7, v2.31.6, v2.32.5, v2.33.6, v2.34.6, v2.35.6, v2.36.4, v2.37.5, v2.38.3, and v2.39.1. X41 D-Sec security scientists Markus Vervier and Eric Sesterhenn as properly as GitLab’s Joern Schneeweisz have been credited with reporting the bugs.
“The most severe issue found lets an attacker to induce a heap-based mostly memory corruption throughout clone or pull functions, which might end result in code execution,” the German cybersecurity organization claimed of CVE-2022-23521.
CVE-2022-41903, also a critical vulnerability, is brought on for the duration of an archive procedure, primary to code execution by way of an integer overflow flaw that occurs when formatting the commit logs.
“On top of that, a substantial variety of integer connected issues was determined which may perhaps direct to denial-of-services cases, out-of-sure reads or merely badly handled corner situations on big input,” X41 D-Sec noted.
When there are no workarounds for CVE-2022-23521, Git is recommending that buyers disable “git archive” in untrusted repositories as a mitigation for CVE-2022-41903 in eventualities where updating to the most recent version is not an possibility.
GitLab, in a coordinated advisory, said it has unveiled variations 15.7.5, 15.6.6, and 15.5.9 for GitLab Community Version (CE) and Organization Edition (EE) to deal with the shortcomings, urging buyers to use the fixes with speedy effect.
