Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Race condition

EUVDB-ID: #VU32694

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2009-4029

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to read and manipulate data.

The (1) dist or (2) distcheck rules in GNU Automake 1.11.1, 1.10.3, and release branches branch-1-4 through branch-1-9, when producing a distribution tarball for a package that uses Automake, assign insecure permissions (777) to directories in the build tree, which introduces a race condition that allows local users to modify the contents of package files, introduce Trojan horse programs, or conduct other attacks before the build is complete.

Mitigation

Update the affected packages.
sys-devel/automake to version: 1.11.6

Vulnerable software versions

Gentoo Linux: All versions
