Linux: >> Linux Kernel >> 2.2.20 Security Vulnerabilities
The _xfs_buf_find function in fs/xfs/xfs_buf.c in the Linux kernel before 3.7.6 does not validate block numbers, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the ability to mount an XFS filesystem containing a metadata inode with an invalid extent map.

fs/ext4/extents.c in the Linux kernel before 3.0 does not mark a modified extent as dirty in certain cases of extent splitting, which allows local users to cause a denial of service (system crash) via vectors involving ext4 umount and mount operations.

The xen_iret function in arch/x86/xen/xen-asm_32.S in the Linux kernel before 3.7.9 on 32-bit Xen paravirt_ops platforms does not properly handle an invalid value in the DS segment register, which allows guest OS users to gain guest OS privileges via a crafted application.

The Linux kernel before 2.6.39 does not properly create transparent huge pages in response to a MAP_PRIVATE mmap system call on /dev/zero, which allows local users to cause a denial of service (system crash) via a crafted application.

Untrusted search path vulnerability in the perf_config function in tools/perf/util/config.c in perf, as distributed in the Linux kernel before 3.1, allows local users to overwrite arbitrary files via a crafted config file in the current working directory.

block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during authorization of SCSI commands, which allows local users to bypass intended access restrictions via an SG_IO ioctl call that leverages overlapping opcodes.

The ipv6_create_tempaddr function in net/ipv6/addrconf.c in the Linux kernel through 3.8 does not properly handle problems with the generation of IPv6 temporary addresses, which allows remote attackers to cause a denial of service (excessive retries and address-generation outage), and consequently obtain sensitive information, via ICMPv6 Router Advertisement (RA) messages.
