More information:

Several vulnerabilities were discovered in advancecomp, a collection of recompression utilities.

  • CVE-2018-1056

    Joonun Jang discovered that the advzip tool was prone to a heap-based buffer overflow. This might allow an attacker to cause a denial-of-service (application crash) or other unspecified impact via a crafted file.

  • CVE-2019-9210

    The png_compress function in in advpng has an integer overflow upon encountering an invalid PNG size, which results in another heap based buffer overflow.

For Debian 8 Jessie, these problems have been fixed in version 1.19-1+deb8u1.

We recommend that you upgrade your advancecomp packages.
