Debian DSA-329-1 : osh - buffer overflows

medium Nessus Plugin ID 15166

Synopsis

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

Description

Steve Kemp discovered that osh, a shell intended to restrict the actions of the user, contains two buffer overflows, in processing environment variables and file redirections. These vulnerabilities could be used to execute arbitrary code, overriding any restrictions placed on the shell.

Solution

For the stable distribution (woody) this problem has been fixed in version 1.7-11woody1.

The old stable distribution (potato) is affected by this problem, and may be fixed in a future advisory on a time-available basis.

We recommend that you update your osh package.
