Scientific Linux Security Update : kernel on SL5.x i386/x86_64
Medium Nessus Plugin ID 60967
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionThis update fixes the following security issues :
- A flaw was found in the Linux kernel's garbage collector for AF_UNIX sockets. A local, unprivileged user could use this flaw to trigger a denial of service (out-of-memory condition). (CVE-2010-4249, Moderate)
- A flaw was found in the Linux kernel's networking subsystem. If the number of packets received exceeded the receiver's buffer limit, they were queued in a backlog, consuming memory, instead of being discarded. A remote attacker could abuse this flaw to cause a denial of service (out-of-memory condition). (CVE-2010-4251, Moderate)
- A missing initialization flaw was found in the ethtool_get_regs() function in the Linux kernel's ethtool IOCTL handler. A local user who has the CAP_NET_ADMIN capability could use this flaw to cause an information leak. (CVE-2010-4655, Low)
This update also fixes several bugs.
The system must be rebooted for this update to take effect.
NOTE: For those who have tested our updated openafs package for SL5, you will need to enable the sl-testing repository to properly do this update. We apologize for this. yum --enablerepo=sl-testing update kernel\* Again, this is only for those who have updated openafs to 1.4.14
SolutionUpdate the affected packages.
