TITLE:
Linux Kernel Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA14713

VERIFY ADVISORY:
http://secunia.com/advisories/14713/

CRITICAL:
Moderately critical

IMPACT:
Exposure of system information, Exposure of sensitive information,
Privilege escalation, DoS, System access

WHERE:
>From remote

OPERATING SYSTEM:
Linux Kernel 2.4.x
http://secunia.com/product/763/
Linux Kernel 2.6.x
http://secunia.com/product/2719/

DESCRIPTION:
Multiple vulnerabilities have been reported in the Linux kernel,
which can be exploited to disclose information, cause a DoS (Denial
of Service), gain escalated privileges, or potentially compromise a
vulnerable system.

1) Some unspecified errors have been reported in the ISO9660
filesystem handler including Rock Ridge and Juliet extensions. These
can be exploited via a specially crafted filesystem to cause a DoS or
potentially corrupt memory leading to execution of arbitrary code.

2) A signedness error in the "bluez_sock_create()" function when
creating bluetooth sockets can potentially be exploited to gain root
privileges on a vulnerable system.

3) An information leak exists in ext2 when creating new directories
and may disclose kernel memory.

4) An error in load_elf_library can be exploited to cause a DoS.

SOLUTION:
Update to version 2.6.11.6.
http://kernel.org/

The vulnerabilities have also been fixed in version 2.4.30-rc2.

PROVIDED AND/OR DISCOVERED BY:
1) Michal Zalewski
2) Ilja van Sprundel
3) Mathieu Lafon
