Debian Security Advisory
DLA-1963-1 poppler -- LTS security update
- Date Reported:
- 17 Oct 2019
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2019-9959, CVE-2019-10871.
- More information:
Two buffer allocation issues were identified in poppler.
An unexpected negative length value can cause an integer overflow, which in turn making it possible to allocate a large memory chunk on the heap with size controlled by an attacker.
The RGB data are considered CMYK data and hence it reads 4 bytes instead of 3 bytes at the end of the image. The fixed version defines SPLASH_CMYK which is the upstream recommended solution.
For Debian 8
Jessie, these problems have been fixed in version 0.26.5-2+deb8u12.
We recommend that you upgrade your poppler packages.
