Debian LTS: DLA-2911-1: apng2gif security update
Summary
Several vulnerabilities have been discovered in apng2gif, a tool for converting
APNG images to animated GIF format. Improper sanitization of user input can
result in denial of service (application crash) or possible execution of
arbitrary code if a malformed image file is processed.
For Debian 9 stretch, these problems have been fixed in version
1.8-0.1~deb9u1.
We recommend that you upgrade your apng2gif packages.
