1) Resource management error (CVE-ID: CVE-2023-24056)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 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
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.
