Detail
A security issue affects the following Ubuntu releases: Ubuntu 5.04 Ubuntu 5.10 Ubuntu 6.06 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 5.04: Ubuntu 5.10: Ubuntu 6.06 LTS: In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Michael Calmer and Marcus Meissner discovered that several krb5 tools did not check the return values from setuid() system calls. On systems that have configured user process limits, it may be possible for an attacker to cause setuid() to fail via resource starvation. In that situation, the tools will not reduce their privilege levels, and will continue operation as the root user. By default, Ubuntu does not ship with user process limits. Please note that these packages are not officially supported by Ubuntu (they are in the 'universe' component of the archive). |
