Debian DLA-947-1 : icu security update

Medium Nessus Plugin ID 100303

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that icu, the International Components for Unicode library, did not correctly validate its input. An attacker could use this problem to trigger an out-of-bound write through a heap-based buffer overflow, thus causing a denial of service via application crash, or potential execution of arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 4.8.1.1-12+deb7u7.

We recommend that you upgrade your icu 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.
