1) Resource management error

EUVDB-ID: #VU72137

Risk: Low

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

CVE-ID: CVE-2023-24056

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to variable duplication in libpkgconf/tuple.c:pkgconf_tuple_parse, which may cause unbounded string expansion. A remote attacker can trick the victim to open a specially crafted .pc file containing a few hundred bytes that can expand to one billion bytes, resulting in a denial of service condition.

Mitigation

Update the affected package pkgconf to the latest version.
