Amazon Linux 2 : git (ALAS-2026-4109)

high Nessus Plugin ID 379820

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of git installed on the remote host is prior to 2.47.3-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-4109 advisory.

Size calculations for very large merge results can overflow, leading to an undersized buffer and heap corruption. (CVE-2026-105437)

Recursive clones can lead to remote code execution through unsafe handling of submodule-related repository metadata. (CVE-2026-111760)

A server can advertise a malformed unborn HEAD, causing unintended file writes during subsequent ref updates with the files ref backend. (CVE-2026-113408)

Certain fast-import features can access arbitrary paths and are now disallowed by default.
(CVE-2026-114466)

Removing more than two GPG signatures from commit messages can corrupt stack memory, potentially causing denial of service during merges. (CVE-2026-114467)

Binary-patch size validation can be bypassed because it checks the encoded input rather than the inflated result, potentially causing an out-of-bounds read and crash. (CVE-2026-114469)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update git' or or 'yum update --advisory ALAS2-2026-4109' to update your system.
