SUSE Linux Distro Vulnerability

SUSE has released an important security update for the Amazon Systems Manager (SSM) Agent, addressing a critical vulnerability (CVE-2025-21613) in the go-git library.

This vulnerability could allow attackers to manipulate git-upload-pack flags under specific circumstances.

go-git is a highly extensible Git implementation library written in pure Go. An argument injection vulnerability was discovered in go-git versions prior to v5.13. Successful exploitation of this vulnerability could allow an attacker to set arbitrary values to git-upload-pack flags.

The update is applicable to several SUSE Linux Enterprise products and Public Cloud Module 12 environments. Users are strongly urged to apply the patch promptly to safeguard their systems.

This only occurs when the file transport protocol is used, as it is the only protocol that shells out to Git binaries.

Key Details of the Security Update

This flaw arises from improper processing of the URL field, creating an opening for argument injection attacks that could compromise system integrity.

The affected Amazon SSM Agent has been updated to version 3.3.1611.0, which resolves the vulnerability. The update ensures secure handling of inputs, mitigating the risk of exploitation.
