 Mandriva Linux Security Advisory                         MDVSA-2014:038
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : kernel
 Date    : February 17, 2014
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in the Linux
 kernel:

 The compat_sys_recvmmsg function in net/compat.c in the Linux kernel
 before 3.13.2, when CONFIG_X86_X32 is enabled, allows local users
 to gain privileges via a recvmmsg system call with a crafted timeout
 pointer parameter (CVE-2014-0038).

 The restore_fpu_checking function in
 arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8
 on the AMD K7 and K8 platforms does not clear pending exceptions
 before proceeding to an EMMS instruction, which allows local users
 to cause a denial of service (task kill) or possibly gain privileges
 via a crafted application (CVE-2014-1438).

 The yam_ioctl function in drivers/net/hamradio/yam.c in the Linux
 kernel before 3.12.8 does not initialize a certain structure member,
 which allows local users to obtain sensitive information from kernel
 memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG
 ioctl call (CVE-2014-1446).

 The updated packages provides a solution for these security issues.
