Description |
MIT Kerberos contains a flaw that may allow a malicious user to overwrite arbitrary files on the system with the permissions of the user running Kerberos, which is potentially root. The issue is due to the program creating world-writeagble symlinks with predictable filenames -- users may overwrite those links to point to any file on the filesystem. This may allow files to be overwritten with the contents of the newly created target, resulting in a loss of integrity.

Solution |
Upgrade to version 1.3.4-r1 or higher, as it has been reported to fix this vulnerability. To do this under Gentoo Linux, run these commands:
# emerge sync
# emerge -pv ">=app-crypt/mit-krb5-1.3.4-r1"
# emerge ">=app-crypt/mit-krb5-1.3.4-r1"
An upgrade is required as there are no known workarounds.
