Debian DLA-2553-2 : xcftools regression update

high Nessus Plugin ID 146360

Synopsis

The remote Debian host is missing a security update.

Description

The patch to address CVE-2019-5086 and CVE-2019-5087 was not portable and did not work on 32 bit processor architectures. This update fixes the problem. For reference, the original advisory text follows.

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, this problem has been fixed in version 1.0.7-6+deb9u2.

We recommend that you upgrade your xcftools packages.

For the detailed security status of xcftools please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/xcftools

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected xcftools package.
