SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 6632)


This update fixes a several security issues and various bugs in the SUSE Linux Enterprise 10 SP 2 kernel. The following security issues were fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to elevate privileges. - On x86_64 systems a information leak of high register contents (upper 32bit) was fixed. (CVE-2009-2910) - The randomness of the ASLR methods used in the kernel was increased. (CVE-2009-3238) - A information leak from the kernel due to uninitialized memory in AGP handling was fixed. (CVE-2009-1192) - A signed comparison in the ax25 sockopt handler was fixed which could be used to crash the kernel or potentially execute code. (CVE-2009-2909) - The execve function in the Linux kernel did not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. (CVE-2009-2848) - Fixed various sockethandler getname leaks, which could disclose memory previously used by the kernel or other userland processes to the local attacker. (CVE-2009-3002) - Multiple buffer overflows in the cifs subsystem in the Linux kernel allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c. (CVE-2009-1633) Also see the RPM changelog for more changes.
