| Description: | Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or leak sensitive data. The Common Vulnerabilities and Exposures project identifies the following problems: Tobias Klein reported a locally exploitable data leak in the snd_seq_oss_synth_make_info() function. This may allow local users to gain access to sensitive information. Zoltan Sogor discovered a coding error in the VFS that allows local users to exploit a kernel memory leak resulting in a denial of service. Eugene Teo reported an integer overflow in the DCCP subsystem that may allow remote attackers to cause a denial of service in the form of a kernel panic. Eugene Teo reported a missing bounds check in the SCTP subsystem. By exploiting an integer overflow in the SCTP_AUTH_KEY handling code, remote attackers may be able to cause a denial of service in the form of a kernel panic. Kel Modderman reported an issue in the tmpfs filesystem that allows local users to crash a system by triggering a kernel BUG() assertion. Alexey Dobriyan discovered an off-by-one-error in the iov_iter_advance function which can be exploited by local users to crash a system, resulting in a denial of service. Vlad Yasevich reported several NULL pointer reference conditions in the SCTP subsystem that can be triggered by entering sctp-auth codepaths when the AUTH feature is inactive. This may allow attackers to cause a denial of service condition via a system panic. Johann Dahm and David Richter reported an issue in the nfsd subsystem that may allow remote attackers to cause a denial of service via a buffer overflow. |
