SuSE 11.1 Security Update : Linux kernel (SAT Patch Numbers 5493 / 5510 / 5511)

High Nessus Plugin ID 57297


The remote SuSE 11 host is missing one or more security updates.


The SUSE Linux Enterprise 11 Service Pack 1 kernel has been updated to version and fixes various bugs and security issues.

- The TCP/IP initial sequence number generation effectively only used 24 bits of 32 to generate randomness, making a brute-force man-in-the-middle attack on TCP/IP connections feasible. The generator was changed to use full 32bit randomness. (CVE-2011-3188)

- Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service.

- A NULL ptr dereference on mounting corrupt hfs filesystems was fixed which could be used by local attackers to crash the kernel. (CVE-2011-2203)

- Added a kernel option to ensure ecryptfs is mounting only on paths belonging to the current ui, which would have allowed local attackers to potentially gain privileges via symlink attacks. (CVE-2011-1833)

- The Generic Receive Offload (GRO) implementation in the Linux kernel allowed remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478. (CVE-2011-1576)

- A name overflow in the hfs filesystem was fixed, where mounting a corrupted hfs filesystem could lead to a stack overflow and code execution in the kernel. This requires a local attacker to be able to mount hfs filesystems. (CVE-2011-4330)

- A bug was found in the way headroom check was performed in udp6_ufo_fragment() function. A remote attacker could use this flaw to crash the system. (CVE-2011-4326)
