DLA-1702-1 advancecomp -- LTS security update
- Date Reported:
- 02 Mar 2019
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 889270, Bug 923416.
In Mitre's CVE dictionary: CVE-2018-1056, CVE-2019-9210.
- More information:
Several vulnerabilities were discovered in advancecomp, a collection of recompression utilities.
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.
The png_compress function in pngex.cc 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.
