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 "
custom_debug"
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.
CVE-2010-3442: Multiple integer overflows in the snd_ctl_ne ...
