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 selinux_ip_postroute_iptables_compat function in security/selinux/hooks.c in the SELinux subsystem in the Linux kernel before 188.8.131.52, and 2.6.28.x before 184.108.40.206, 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 220.127.116.11. (CVE-2009-1184)
The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.
The (1) agp_generic_alloc_page and (2) agp_generic_alloc_pages functions in drivers/char/agp/generic.c in the agp subsystem in the Linux kernel before 2.6.30-rc3 do not zero out pages that may later be available to a user-space process, which allows local users to obtain sensitive information by reading these pages. (CVE-2009-1192)
The ABI in the Linux kernel 2.6.28 and earlier on s390, powerpc, sparc64, and mips 64-bit platforms requires that a 32-bit argument in a 64-bit register was properly sign extended when sent from a user-mode application, but cannot verify this, which allows local users to cause a denial of service (crash) or possibly gain privileges via a crafted system call. (CVE-2009-0029)
The __inet6_check_established function in net/ipv6/inet6_hashtables.c in the Linux kernel before 2.6.29, when Network Namespace Support (aka NET_NS) is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via vectors involving IPv6 packets. (CVE-20090-1360)
The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 18.104.22.168, 2.6.29 before 22.214.171.124, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the generic_file_splice_write, splice_from_pipe, and ocfs2_file_splice_write functions. (CVE-2009-1961)
Integer underflow in the e1000_clean_rx_irq function in drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel before 2.6.30-rc8, the e1000e driver in the Linux kernel, and Intel Wired Ethernet (aka e1000) before 7.5.5 allows remote attackers to cause a denial of service (panic) via a crafted frame size.
The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 126.96.36.199 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver. (CVE-2009-1630)
Additionally, the kernel package was updated to the Linux upstream stable version 188.8.131.52.
