local privilege escalation, remote denial of service
Solution
Please Install the Updated Packages.
Insight
The openSUSE 11.3 kernel was updated to fix various bugs and security issues. Following security issues have been fixed: CVE-2010-4347: A local user could inject ACPI code into the kernel via the world-writable &quot custom_debug&quot file, allowing local privilege escalation. CVE-2010-4258: A local attacker could use a Oops (kernel crash) caused by other flaws to write a 0 byte to a attacker controlled address in the kernel. This could lead to privilege escalation together with other issues. CVE-2010-4157: A 32bit vs 64bit integer mismatch in gdth_ioctl_alloc could lead to memory corruption in the GDTH driver. CVE-2010-4165: The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel did 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-2010-4164: A remote (or local) attacker communicating over X.25 could cause a kernel panic by attempting to negotiate malformed facilities. CVE-2010-4175: A local attacker could cause memory overruns in the RDS protocol stack, potentially crashing the kernel. So far it is considered not to be exploitable. CVE-2010-4169: Use-after-free vulnerability in mm/mprotect.c in the Linux kernel allowed local users to cause a denial of service via vectors involving an mprotect system call. CVE-2010-3874: A minor heap overflow in the CAN network module was fixed. Due to nature of the memory allocator it is likely not exploitable. CVE-2010-4158: A memory information leak in Berkeley packet filter rules allowed local attackers to read uninitialized memory of the kernel stack. CVE-2010-4162: A local denial of service in the blockdevice layer was fixed. CVE-2010-4163: By submitting certain I/O requests with 0 length, a local user could have caused a kernel panic. CVE-2010-0435: The Hypervisor in KVM 83, when the Intel VT-x extension is enabled, allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via vectors related to instruction emulation. CVE-2010-3861: The ethtool_get_rxnfc function in net/core/ethtool.c in the Linux kernel did not initialize a certain block of heap memory, which allowed local users to obtain potentially sensitive information via an ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt value.
