Advisories MDKSA-2007:060: Updated kernel packages fix multiple vulnerabilities and bugs

[paul]

Some vulnerabilities were discovered and corrected in the Linux 2.6

kernel:

 

The 2.6.17 kernel and earlier, when running on IA64 and SPARC platforms

would allow a local user to cause a DoS (crash) via a malformed ELF file

(CVE-2006-4538).

 

The mincore function in the Linux kernel did not properly lock access to

user space, which has unspecified impact and attack vectors, possibly

related to a deadlock (CVE-2006-4814).

 

An unspecified vulnerability in the listxattr system call, when a "bad

inode" is present, could allow a local user to cause a DoS (data

corruption) and possibly gain privileges via unknown vectors

(CVE-2006-5753).

 

The zlib_inflate function allows local users to cause a crash via a

malformed filesystem that uses zlib compression that triggers memory

corruption (CVE-2006-5823).

 

The ext3fs_dirhash function could allow local users to cause a DoS

(crash) via an ext3 stream with malformed data structures

(CVE-2006-6053).

 

When SELinux hooks are enabled, the kernel could allow a local user to

cause a DoS (crash) via a malformed file stream that triggers a NULL

pointer derefernece (CVE-2006-6056).

 

The key serial number collision avoidance code in the key_alloc_serial

function in kernels 2.6.9 up to 2.6.20 allows local users to cause a

crash via vectors thatr trigger a null dereference (CVE-2007-0006).

 

The Linux kernel version 2.6.13 to 2.6.20.1 allowed a remote attacker

to cause a DoS (oops) via a crafted NFSACL2 ACCESS request that

triggered a free of an incorrect pointer (CVE-2007-0772).

 

A local user could read unreadable binaries by using the interpreter

(PT_INTERP) functionality and triggering a core dump; a variant of

CVE-2004-1073 (CVE-2007-0958).

 

The provided packages are patched to fix these vulnerabilities. All

users are encouraged to upgrade to these updated kernels immediately

and reboot to effect the fixes.

 

In addition to these security fixes, other fixes have been included

such as:

 

- add PCI IDs for cciss driver (HP ML370G5 / DL360G5)

- fixed a mssive SCSI reset on megasas (Dell PE2960)

- increased port-reset completion delay for HP controllers (HP ML350)

- NUMA rnage fixes for x86_64

- various netfilter fixes
