SuSE 10 Security Update : the debug kernel (ZYPP Patch Number 6778)

Description

This update fixes various bugs and some security issues in the SUSE Linux Enterprise 10 SP 3 kernel.

The following security issues were fixed :

  • drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. (CVE-2009-4536)

  • drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets. (CVE-2009-4538)

  • Missing CAP_NET_ADMIN checks in the ebtables netfilter code might have allowed local attackers to modify bridge firewall settings. (CVE-2010-0007)
