SuSE 10 Security Update : Linux kernel (i386) (ZYPP Patch Number 2097)
high Nessus Plugin ID 29485
Synopsis
The remote SuSE 10 host is missing a security-related patch.Description
This kernel update fixes the following security problems :- A double userspace copy in a SCTP ioctl allows local attackers to overflow a buffer in the kernel, potentially allowing code execution and privilege escalation. [#199441]. (CVE-2006-3745)
- Local attackers were able to crash PowerPC systems with PPC970 processor using a not correctly disabled privileged instruction ('attn'). [#197810].
(CVE-2006-4093)
- Remote attackers able to access an NFS of a ext2 or ext3 filesystem can cause a denial of service (file system panic) via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle (inode number), which triggers an error and causes an exported directory to be remounted read-only. [#192988].
(CVE-2006-3468)
and the following non security bugs :
- XEN patches/fixes :
- kunmap_atomic() must zap the PTE to avoid dangling references.
- Fix oops on io scheduler unload on a process without ioc (backport)
