New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis kernel update fixes various bugs and also several security issues :
CVE-2008-4576: Fixed a crash in SCTP INIT-ACK, on mismatch between SCTP AUTH availability. This might be exploited remotely for a denial of service (crash) attack.
CVE-2008-3833: The generic_file_splice_write function in fs/splice.c in the Linux kernel does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by splicing into an inode in order to create an executable file in a setgid directory.
CVE-2008-4210: fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable file in a setgid directory through the (1) truncate or (2) ftruncate function in conjunction with memory-mapped I/O.
CVE-2008-4302: fs/splice.c in the splice subsystem in the Linux kernel before 188.8.131.52 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool.
CVE-2008-3528: The ext filesystem code fails to properly handle corrupted data structures. With a mounted filesystem image or partition that have corrupted dir->i_size and dir->i_blocks, a user performing either a read or write operation on the mounted image or partition can lead to a possible denial of service by spamming the logfile.
CVE-2007-6716: fs/direct-io.c in the dio subsystem in the Linux kernel did not properly zero out the dio struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio test.
CVE-2008-3525: Added missing capability checks in sbni_ioctl().
CVE-2008-3272: Fixed range checking in the snd_seq OSS ioctl, which could be used to leak information from the kernel.
CVE-2008-2931: The do_change_type function in fs/namespace.c did not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.
CVE-2008-2812: Various NULL ptr checks have been added to tty op functions, which might have been used by local attackers to execute code. We think that this affects only devices openable by root, so the impact is limited.
CVE-2008-1673: Added range checking in ASN.1 handling for the CIFS and SNMP NAT netfilter modules.
CVE-2008-3527: arch/i386/kernel/sysenter.c in the Virtual Dynamic Shared Objects (vDSO) implementation in the Linux kernel before 2.6.21 did not properly check boundaries, which allows local users to gain privileges or cause a denial of service via unspecified vectors, related to the install_special_mapping, syscall, and syscall32_nopage functions.
SolutionUpdate the affected kernel packages.
