Hmm - some more vulnerabilities... :-(
http://secunia.com/advisories/14295/
- nls_ascii.c buffer overflow (potential crash kernel exploit)
- error in netfilter (potential crash kernel exploit or bypass of firewall rules)
CANs assigned:
CAN-2005-0529
CAN-2005-0530
CAN-2005-0531
CAN-2005-0532
From Ubuntu's latest:
Georgi Guninski discovered a buffer overflow in the ATM driver. The
atm_get_addr() function does not validate its arguments sufficiently,
which could allow a local attacker to overwrite large portions of
kernel memory by supplying a negative length argument. This could
eventually lead to arbitrary code execution. (CAN-2005-0531)
Georgi Guninski also discovered three other integer comparison
problems in the TTY layer, in the /proc interface and the ReiserFS
driver. However, the previous Ubuntu security update (kernel version
2.6.8.1-16.11) already contained a patch which checks the arguments to
these functions at a higher level and thus prevents these flaws from
being exploited. (CAN-2005-0529, CAN-2005-0530, CAN-2005-0532)

gentoo-dev-sources unaffected
Everything seems to have been patched or upgraded to 2.6.11; mips-sources
branches remain that still need patching so CCing Kumba.
