SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 7516)
High Nessus Plugin ID 57212
SynopsisThe remote SuSE 10 host is missing a security-related patch.
DescriptionThis kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes several security issues and bugs.
The following security issues were fixed :
- The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions.
(CVE-2011-1017 / CVE-2011-1012)
- Boundschecking was missing in AARESOLVE_OFFSET, which allowed local attackers to overwrite kernel memory and so escalate privileges or crash the kernel.
- When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. (CVE-2011-1585)
- Kernel information via the TPM devices could by used by local attackers to read kernel memory. (CVE-2011-1160)
- The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code.
- In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory. (CVE-2011-1180)
- A system out of memory condition (denial of service) could be triggered with a large socket backlog, exploitable by local users. This has been addressed by backlog limiting. (CVE-2010-4251)
- The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values. (CVE-2011-1016)
- 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.
- Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs.
- The code for evaluating Mac partitions (in fs/partitions/mac.c) contained a bug that could crash the kernel for certain corrupted Mac partitions.
- 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-2011-1163)
- 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-2011-1476)
- 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-2011-1477)
- A information leak in the XFS geometry calls could be used by local attackers to gain access to kernel information. (CVE-2011-0191)
- The sctp_rcv_ootb function in the SCTP implementation in the Linux kernel allowed remote attackers to cause a denial of service (infinite loop) via (1) an Out Of The Blue (OOTB) chunk or (2) a chunk of zero length.
