Debian DLA-1363-1 : ghostscript security update

Medium Nessus Plugin ID 109347

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that the set_text_distance function in base/gdevpdts.c in the pdfwrite component in Ghostscript does not prevent overflows in text-positioning calculation, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document.

For Debian 7 'Wheezy', these problems have been fixed in version 9.05~dfsg-6.3+deb7u8.

We recommend that you upgrade your ghostscript packages.

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 packages.
