Debian DSA-1202-1 : screen - programming error

low Nessus Plugin ID 22934

Synopsis

The remote Debian host is missing a security-related update.

Description

'cstone' and Rich Felker discovered that specially crafted UTF-8 sequences may lead an out of bands memory write when displayed inside the screen terminal multiplexer, allowing denial of service and potentially the execution of arbitrary code.

Solution

Upgrade the screen package.

For the stable distribution (sarge) this problem has been fixed in version 4.0.2-4.1sarge1. Due to technical problems with the security buildd infrastructure this update lacks a build for the Sun Sparc architecture. It will be released as soon as the problems are resolved.
