Mandrake Linux Security Advisory : kernel (MDKSA-2007:078)
high Nessus Plugin ID 24944
Synopsis
The remote Mandrake Linux host is missing one or more security updates.Description
Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :When SELinux hooks are enabled, the kernel could allow a local user to cause a DoS (crash) via a malformed file stream that triggers a NULL pointer derefernece (CVE-2006-6056).
Multiple buffer overflows in the (1) read and (2) write handlers in the Omnikey CardMan 4040 driver in the Linux kernel before 2.6.21-rc3 allow local users to gain privileges. (CVE-2007-0005)
The Linux kernel version 2.6.13 to 2.6.20.1 allowed a remote attacker to cause a DoS (oops) via a crafted NFSACL2 ACCESS request that triggered a free of an incorrect pointer (CVE-2007-0772).
A local user could read unreadable binaries by using the interpreter (PT_INTERP) functionality and triggering a core dump; a variant of CVE-2004-1073 (CVE-2007-0958).
The ipv6_getsockopt_sticky function in net/ipv6/ipv6_sockglue.c in the Linux kernel before 2.6.20.2 allows local users to read arbitrary kernel memory via certain getsockopt calls that trigger a NULL dereference. (CVE-2007-1000)
Buffer overflow in the bufprint function in capiutil.c in libcapi, as used in Linux kernel 2.6.9 to 2.6.20 and isdn4k-utils, allows local users to cause a denial of service (crash) and possibly gain privileges via a crafted CAPI packet. (CVE-2007-1217)
The do_ipv6_setsockopt function in net/ipv6/ipv6_sockglue.c in Linux kernel 2.6.17, and possibly other versions, allows local users to cause a denial of service (oops) by calling setsockopt with the IPV6_RTHDR option name and possibly a zero option length or invalid option value, which triggers a NULL pointer dereference.
(CVE-2007-1388)
net/ipv6/tcp_ipv6.c in Linux kernel 2.4 and 2.6.x up to 2.6.21-rc3 inadvertently copies the ipv6_fl_socklist from a listening TCP socket to child sockets, which allows local users to cause a denial of service (OOPS) or double-free by opening a listeing IPv6 socket, attaching a flow label, and connecting to that socket. (CVE-2007-1592)
