SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SUSE-SA:2005:003 (kernel).
Several exploitable security problems were identified and fixed in the Linux kernel, the core of every SUSE Linux product.
- Due to missing locking in the sys_uselib system call a local attacker can gain root access. This was found by Paul Starzetz and is tracked by the Mitre CVE ID CVE-2004-1235.
- Paul Starzetz also found a race condition in SMP page table handling which could lead to a local attacker gaining root access on SMP machines. This is tracked by the Mitre CVE ID CVE-2005-0001.
- A local denial of service was found in the auditing subsystem which have lead a local attacker crashing the machine. This was reported and fixed by Redhat.
- The sendmsg / cmsg fix from the previous kernel update was faulty on 64bit systems with 32bit compatibility layer and could lead to 32bit applications not working correctly on those 64bit systems.
- The smbfs security fixes from a before-previous kernel update were faulty for some file write cases.
- A local denial of service with Direct I/O access to NFS file systems could lead a local attacker to crash a machine with NFS mounts.
- grsecurity reported a signed integer problem in the SCSI ioctl handling which had a missing boundary check.
Due to C language specifics, this evaluation was not correct and there actually is no problem in this code.
The signed / unsigned mismatch was fixed nevertheless.
- Several more small non security problems were fixed.
NOTE: Two days ago we released the Service Pack 1 for the SUSE Linux Enterprise Server 9. This kernel update contains fixes for the SUSE Linux Enterprise Server 9 GA version kernel line.
A fix for the Service Pack 1 version line will be available shortly.
