This was previously reported to Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=567052 and upstream: http://krbdev.mit.edu/rt/Ticket/Display.html?user=guest&pass=guest&id=5998 By the looks of the upstream reports, this is just a denial of service, nothing more. It was also assigned CVE-2010-0629. Looking at the commit, this would have been fixed in 1.6.4, which means Fedora 11 is vulnerable. This issue also does not affect Red Hat Enterprise Linux 4 or earlier as the variable in question (handle) isn't referenced after it is freed. This issue does affect Red Hat Enterprise Linux 5. Public via: [1] http://web.mit.edu/Kerberos/advisories/MITKRB5-SA-2010-003.txt This issue has been addressed in following products: Red Hat Enterprise Linux 5 Via RHSA-2010:0343 https://rhn.redhat.com/errata/RHSA-2010-0343.html krb5-1.6.3-29.fc11 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/krb5-1.6.3-29.fc11 krb5-1.6.3-29.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report. |
