Description

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 Debian 9 stretch, this problem has been fixed in version 2.6.3-3.2+deb9u2.
