Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-2010 advisory.

- The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel before 2.6.37-rc2 does not properly restrict TCP_MAXSEG (aka MSS) values, which allows local users to cause a denial of service (OOPS) via a setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a signed integer. (CVE-2010-4165)

- Use-after-free vulnerability in mm/mprotect.c in the Linux kernel before 2.6.37-rc2 allows local users to cause a denial of service via vectors involving an mprotect system call. (CVE-2010-4169)

- The wait_for_unix_gc function in net/unix/garbage.c in the Linux kernel before 2.6.37-rc3-next-20101125 does not properly select times for garbage collection of inflight sockets, which allows local users to cause a denial of service (system hang) via crafted use of the socketpair and sendmsg system calls for SOCK_SEQPACKET sockets. (CVE-2010-4249)

- The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel before 2.6.37-rc7 allows local users to cause a denial of service (panic) via a zero-length I/O request in a device ioctl to a SCSI device, related to an unaligned map. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4163. (CVE-2010-4668)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
