TITLE:
Linux Kernel Denial of Service and Privilege Escalation
SECUNIA ADVISORY ID:
SA36763
VERIFY ADVISORY:
http://secunia.com/advisories/36763/
DESCRIPTION:
Some vulnerabilities have been reported in the Linux Kernel, which
can be exploited by malicious, local users to gain escalated
privileges and by malicious people to cause a DoS (Denial of
Service).
1) An error exists within the "find_ie()" function in
net/wireless/scan.c, which can be exploited to trigger an infinite
loop by sending specially crafted packets.
Note: This does not affect versions prior to 2.6.30.
2) A boundary error within the "perf_copy_attr()" function in
kernel/perf_counter.c can be exploited to cause a buffer overflow by
e.g. passing specially crafted data via the "perf_counter_open()"
syscall.
Note: This does not affect versions prior to 2.6.31.
SOLUTION:
Fixed in the GIT repository.
PROVIDED AND/OR DISCOVERED BY:
1) Bob Copeland
