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.
