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]

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Automake
Other software / Other software solutions

Vendor: GNU

Description

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

The "make distcheck" rule in GNU Automake before 1.11.6 and 1.12.x before 1.12.2 grants world-writable permissions to the extraction directory, which introduces a race condition that allows local users to execute arbitrary code via unspecified vectors.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Automake: 1.11.1 - 1.11.5
