1st November, 2006
mutt vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.10
- Ubuntu 6.06 LTS
- Ubuntu 5.10
Details
Race conditions were discovered in mutt's handling of temporary files.
Under certain conditions when using a shared temp directory (the
default), other local users could overwrite arbitrary files owned by the
user running mutt. This vulnerability is more likely when the temp
directory is over NFS.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.10:
- mutt 1.5.12-1ubuntu1.1
- Ubuntu 6.06 LTS:
- mutt 1.5.11-3ubuntu2.2
- Ubuntu 5.10:
- mutt 1.5.9-2ubuntu1.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart mutt to effect the
necessary changes.
