New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionSome vulnerabilities were discovered and corrected in the Linux 2.6 kernel :
The clone system call in the Linux kernel 2.6.28 and earlier allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit.
fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before 188.8.131.52 allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index. (CVE-2009-0269)
The audit_syscall_entry function in the Linux kernel 184.108.40.206 and earlier on the x86_64 platform does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls, a related issue to CVE-2009-0342 and CVE-2009-0343. (CVE-2009-0834)
The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel 220.127.116.11 and earlier on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod, a related issue to CVE-2009-0342 and CVE-2009-0343. (CVE-2009-0835)
The selinux_ip_postroute_iptables_compat function in security/selinux/hooks.c in the SELinux subsystem in the Linux kernel before 18.104.22.168, and 2.6.28.x before 22.214.171.124, when compat_net is enabled, omits calls to avc_has_perm for the (1) node and (2) port, which allows local users to bypass intended restrictions on network traffic. NOTE: this was incorrectly reported as an issue fixed in 126.96.36.199. (CVE-2009-1184)
Additionally, along with other things, this kernel update adds support for D-Link DWM 652 3.5G, some Intel gigabit network chipsets, Avermedia PCI pure analog (M135A), fixes a bug causing SQLite performance regression, and has some updated ALSA drivers. Check the package changelog for details.
