The openSUSE 11.4 kernel was updated to 2.6.37.6 fixing lots of bugs and security issues.

Following security issues have been fixed: CVE-2011-1493: In the rose networking stack, when parsing the FAC_NATIONAL_DIGIS facilities field, it was possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. Check against ROSE_MAX_DIGIS to prevent overflows, and abort facilities parsing on failure.

CVE-2011-1182: Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs.

CVE-2011-1478: An issue in the core GRO code where an skb belonging to an unknown VLAN is reused could result in a NULL pointer dereference.

CVE-2011-1476: Specially crafted requests may be written to /dev/sequencer resulting in an underflow when calculating a size for a copy_from_user() operation in the driver for MIDI interfaces. On x86, this just returns an error, but it could have caused memory corruption on other architectures. Other malformed requests could have resulted in the use of uninitialized variables.
