Package        : libcpanel-json-xs-perl
CVE ID         : CVE-2025-40929

Michael Hudak discovered a flaw in libcpanel-json-xs-perl, a module for
fast and correct serialising to JSON. An integer buffer overflow causing
a segfault when parsing specially crafted JSON, may allow an attacker to
mount a denial-of-service attack or cause other unspecified impact.

For the oldstable distribution (bookworm), this problem has been fixed
in version 4.35-1+deb12u1.

For the stable distribution (trixie), this problem has been fixed in
version 4.39-2~deb13u1.

We recommend that you upgrade your libcpanel-json-xs-perl packages.
