Debian LTS Advisory DLA-2553-1 [email protected]
https://www.debian.org/lts/security/ Markus Koschany

Package : xcftools
Version : 1.0.7-6+deb9u1
CVE ID : CVE-2019-5086 CVE-2019-5087
Debian Bug : 945317

Claudio Bozzato of Cisco Talos discovered an exploitable integer overflow
vulnerability in the flattenIncrementally function in the xcf2png and xcf2pnm
binaries of xcftools. An integer overflow can occur while walking through tiles
that could be exploited to corrupt memory and execute arbitrary code. In order
to trigger this vulnerability, a victim would need to open a specially crafted
XCF file.

For Debian 9 stretch, these problems have been fixed in version
1.0.7-6+deb9u1.

We recommend that you upgrade your xcftools packages.
