Vulnerability Assessment Details

[DSA022] DSA-022-1 exmh

Vulnerability Assessment Summary
DSA-022-1 exmh

Detailed Explanation for this Vulnerability Assessment
Former versions of the exmh program used /tmp for storing
temporary files. No checks were made to ensure that nobody placed a symlink
with the same name in /tmp in the meantime and thus was vulnerable to a symlink
attack. This could lead to a malicious local user being able to overwrite any
file writable by the user executing exmh. Upstream developers have reported and
fixed this. The exmh program now use /tmp/login unless TMPDIR or EXMHTMPDIR
is set.

We recommend you upgrade your exmh packages immediately.
