The perf subsystem in the kernel package 2.6.32-122.el6.x86_64 in Red Hat Enterprise Linux (RHEL) 6 does not properly handle NMIs, which might allow local users to cause a denial of service (excessive log messages) via unspecified vectors.

The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for write access to the (1) set_ftrace_pid or (2) set_graph_function file, and then making an lseek system call.

The ext4_orphan_del function in fs/ext4/namei.c in the Linux kernel before 3.7.3 does not properly handle orphan-list entries for non-journal filesystems, which allows physically proximate attackers to cause a denial of service (system hang) via a crafted filesystem on removable media, as demonstrated by the e2fsprogs tests/f_orphan_extents_inode/image.gz test.

The do_video_set_spu_palette function in fs/compat_ioctl.c in the Linux kernel before 3.6.5 on unspecified architectures lacks a certain error check, which might allow local users to obtain sensitive information from kernel stack memory via a crafted VIDEO_SET_SPU_PALETTE ioctl call on a /dev/dvb device.

The default configuration for IPA servers in Red Hat Enterprise Linux 6, when revoking a certificate from an Identity Management replica, does not properly update another Identity Management replica, which causes inconsistent Certificate Revocation Lists (CRLs) to be used and might allow remote attackers to bypass intended access restrictions via a revoked certificate.

MariaDB 5.5.x before 5.5.30, 5.3.x before 5.3.13, 5.2.x before 5.2.15, and 5.1.x before 5.1.68, and Oracle MySQL 5.1.69 and earlier, 5.5.31 and earlier, and 5.6.11 and earlier allows remote attackers to cause a denial of service (crash) via a crafted geometry feature that specifies a large number of points, which is not properly handled when processing the binary representation of this feature, related to a numeric calculation error.

The sanitize helper in lib/action_controller/vendor/html-scanner/html/sanitizer.rb in the Action Pack component in Ruby on Rails before 2.3.18, 3.0.x and 3.1.x before 3.1.12, and 3.2.x before 3.2.13 does not properly handle encoded : (colon) characters in URLs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted scheme name, as demonstrated by including a : sequence.

The sanitize_css method in lib/action_controller/vendor/html-scanner/html/sanitizer.rb in the Action Pack component in Ruby on Rails before 2.3.18, 3.0.x and 3.1.x before 3.1.12, and 3.2.x before 3.2.13 does not properly handle \n (newline) characters, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via crafted Cascading Style Sheets (CSS) token sequences.

The Active Record component in Ruby on Rails 2.3.x before 2.3.18, 3.1.x before 3.1.12, and 3.2.x before 3.2.13 processes certain queries by converting hash keys to symbols, which allows remote attackers to cause a denial of service via crafted input to a where method.

The udf_encode_fh function in fs/udf/namei.c in the Linux kernel before 3.6 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory via a crafted application.

The ATM implementation in the Linux kernel before 3.6 does not initialize certain structures, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.

The Bluetooth RFCOMM implementation in the Linux kernel before 3.6 does not properly initialize certain structures, which allows local users to obtain sensitive information from kernel memory via a crafted application.

The Bluetooth protocol stack in the Linux kernel before 3.6 does not properly initialize certain structures, which allows local users to obtain sensitive information from kernel stack memory via a crafted application that targets the (1) L2CAP or (2) HCI implementation.

The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel before 3.6 has an incorrect return value in certain circumstances, which allows local users to obtain sensitive information from kernel stack memory via a crafted application that leverages an uninitialized pointer argument.

The copy_to_user_auth function in net/xfrm/xfrm_user.c in the Linux kernel before 3.6 uses an incorrect C library function for copying a string, which allows local users to obtain sensitive information from kernel heap memory by leveraging the CAP_NET_ADMIN capability.

net/xfrm/xfrm_user.c in the Linux kernel before 3.6 does not initialize certain structures, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability.

HP Linux Imaging and Printing (HPLIP) through 3.12.4 allows local users to overwrite arbitrary files via a symlink attack on the (1) /tmp/hpcupsfilterc_#.bmp, (2) /tmp/hpcupsfilterk_#.bmp, (3) /tmp/hpcups_job#.out, (4) /tmp/hpijs_#####.out, or (5) /tmp/hpps_job#.out temporary file, a different vulnerability than CVE-2011-2722.

The ExecShield feature in a certain Red Hat patch for the Linux kernel in Red Hat Enterprise Linux (RHEL) 5 and 6 and Fedora 15 and 16 does not properly handle use of many shared libraries by a 32-bit executable file, which makes it easier for context-dependent attackers to bypass the ASLR protection mechanism by leveraging a predictable base address for one of these libraries.

The chase_port function in drivers/usb/serial/io_ti.c in the Linux kernel before 3.7.4 allows local users to cause a denial of service (NULL pointer dereference and system crash) via an attempted /dev/ttyUSB read or write operation on a disconnected Edgeport USB serial converter.

Buffer overflow in the VFAT filesystem implementation in the Linux kernel before 3.3 allows local users to gain privileges or cause a denial of service (system crash) via a VFAT write operation on a filesystem with the utf8 mount option, which is not properly handled during UTF-8 to UTF-16 conversion.
