Package : libonig Version : 5.9.5-3.2+deb8u2 CVE ID : CVE-2019-13224 Debian Bug : 931878

A use-after-free in onig_new_deluxe() in regext.c allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that gets handled by onig_new_deluxe().

For Debian 8 "Jessie", this problem has been fixed in version 5.9.5-3.2+deb8u2.

We recommend that you upgrade your libonig packages.
