The maintainers of the Git supply code model management system have launched updates to remediate two crucial vulnerabilities that might be exploited by a malicious actor to realize distant code execution.

The failings, 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 v2.39.0.

“Probably the most extreme subject found permits an attacker to set off a heap-based reminiscence corruption throughout clone or pull operations, which could lead to code execution,” the German cybersecurity firm stated of CVE-2022-23521.

CVE-2022-41903, additionally a crucial vulnerability, is triggered throughout an archive operation, resulting in code execution by means of an integer overflow flaw that arises when formatting the commit logs.

“Moreover, an enormous variety of integer associated points was recognized which can result in denial-of-service conditions, out-of-bound reads or just badly dealt with nook instances on massive enter,” X41 D-Sec famous.
