| Beschreibung: | Description:
The remote host is missing an update to kernel
announced via advisory MDKSA-2006:040.
A number of vulnerabilities were discovered and corrected in the Linux
2.6 kernel:
The udp_v6_get_port function in udp.c, when running IPv6, allows local
users to cause a Denial of Service (infinite loop and crash)
(CVE-2005-2973).
The mq_open system call in certain situations can decrement a counter
twice as a result of multiple calls to the mntput function when the
dentry_open function call fails, allowing a local user to cause a DoS
(panic) via unspecified attack vectors (CVE-2005-3356).
The procfs code allows attackers to read sensitive kernel memory via
unspecified vectors in which a signed value is added to an unsigned
value (CVE-2005-4605).
A buffer overflow in sysctl allows local users to cause a DoS and
possibly execute arbitrary code via a long string, which causes sysctl
to write a zero byte outside the buffer (CVE-2005-4618).
A buffer overflow in the CA-driver for TwinHan DST Frontend/Card allows
local users to cause a DoS (crash) and possibly execute arbitrary code
by reading more than eight bytes into an eight byte long array
(CVE-2005-4639).
dm-crypt does not clear a structure before it is freed, which leads to
a memory disclosure that could allow local users to obtain sensitive
information about a cryptographic key (CVE-2006-0095).
Remote attackers can cause a DoS via unknown attack vectors related to
an extra dst release when ip_options_echo fails in icmp.c
(CVE-2006-0454).
In addition to these security fixes, other fixes have been included
such as:
- support for mptsas
- fix for IPv6 with sis190
- a problem with the time progressing twice as fast
- a fix for Audigy 2 ZS Video Editor sample rates
- a fix for a supermount crash when accessing a supermount-ed CD/DVD
drive
- a fix for improperly unloading sbp2 module
The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.
To update your kernel, please follow the directions located at:
http://www.mandriva.com/en/security/kernelupdate
Affected: 2006.0
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
