Debian DSA-3830-1 : icu - security update

high Nessus Plugin ID 99484

Language:

Synopsis

The remote Debian host is missing a security-related 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.

Solution

Upgrade the icu packages.

For the stable distribution (jessie), these problems have been fixed in version 52.1-8+deb8u5.

For the upcoming stable (stretch) and unstable (sid) distributions, these problems have been fixed in version 57.1-6.
