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.
