Debian Security Advisory DSA-4561-1 [email protected]

Package : fribidi
CVE ID : CVE-2019-18397
Debian Bug : 944327

Alex Murray discovered a stack-based buffer overflow vulnerability in
fribidi, an implementation of the Unicode Bidirectional Algorithm
algorithm, which could result in denial of service or potentially the
execution of arbitrary code, when processing a large number of unicode
isolate directional characters.

For the stable distribution (buster), this problem has been fixed in
version 1.0.5-3.1+deb10u1.

We recommend that you upgrade your fribidi packages.

For the detailed security status of fribidi please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/fribidi
