-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:040 http://www.mandriva.com/security/ _______________________________________________________________________ Package : kernel Date : February 17, 2006 Affected: 2006.0 _______________________________________________________________________ Problem Description: 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.
