local privilege escalation, remote denial of service

Please Install the Updated Packages.

The openSUSE 11.2 kernel was updated to fix lots of security issues. This will probably be the last 11.2 kernel update released by the SUSE Security Team, as our suppport for 11.2 ends in 1 month. Following security issues were 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-2011-1082: The epoll subsystem in Linux did not prevent users from creating circular epoll file structures, potentially leading to a denial of service (kernel deadlock). CVE-2011-1163: The code for evaluating OSF partitions (in fs/partitions/osf.c) contained a bug that leaks data from kernel heap memory to userspace for certain corrupted OSF partitions. CVE-2011-1012: The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained a bug that could crash the kernel for certain corrupted LDM partitions. CVE-2011-1010: The code for evaluating Mac partitions (in fs/partitions/mac.c) contained a bug that could crash the kernel for certain corrupted Mac partitions. 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. CVE-2011-1477: Due to a failure to validate user-supplied indexes in the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted ioctl request could have been sent to /dev/sequencer, resulting in reading and writing beyond the bounds of heap buffers, and potentially allowing privilege escalation. CVE-2011-1090: A page allocator issue in NFS v4 ACL handling that could lead to a denial of service (crash) was fixed. CVE-2010-3880: net/ipv4/inet_diag.c in the Linux kernel did not properly audit INET_DIAG bytecode, which allowed local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message that contains multiple attribute elements, as demonst ...
