Debian Security Advisory DSA-4777-1 [email protected]

Package : freetype
CVE ID : CVE-2020-15999
Debian Bug : 972586

Sergei Glazunov discovered a heap-based buffer overflow vulnerability in
the handling of embedded PNG bitmaps in FreeType. Opening malformed
fonts may result in denial of service or the execution of arbitrary
code.

For the stable distribution (buster), this problem has been fixed in
version 2.9.1-3+deb10u2.

We recommend that you upgrade your freetype packages.

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