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.

System Security Services Daemon (SSSD) before 1.9.4, when (1) creating, (2) copying, or (3) removing a user home directory tree, allows local users to create, modify, or delete arbitrary files via a symlink attack on another user's files.

The translate_desc function in drivers/vhost/vhost.c in the Linux kernel before 3.7 does not properly handle cross-region descriptors, which allows guest OS users to obtain host OS privileges by leveraging KVM guest OS privileges.

The cipso_v4_validate function in net/ipv4/cipso_ipv4.c in the Linux kernel before 3.4.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an IPOPT_CIPSO IP_OPTIONS setsockopt system call.

arch/x86/include/asm/pgtable.h in the Linux kernel before 3.6.2, when transparent huge pages are used, does not properly support PROT_NONE memory regions, which allows local users to cause a denial of service (system crash) via a crafted application.

A certain Red Hat build of the pam_ssh_agent_auth module on Red Hat Enterprise Linux (RHEL) 6 and Fedora Rawhide calls the glibc error function instead of the error function in the OpenSSH codebase, which allows local users to obtain sensitive information from process memory or possibly gain privileges via crafted use of an application that relies on this module, as demonstrated by su and sudo.

Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet.

Stack-based buffer overflow in libpixman, as used in Pale Moon before 15.4 and possibly other products, has unspecified impact and context-dependent attack vectors. NOTE: this issue might be resultant from an integer overflow in the fast_composite_scaled_bilinear function in pixman-inlines.h, which triggers an infinite loop.

Unspecified vulnerability in the Server component in Oracle MySQL 5.1.66 and earlier, and 5.5.28 and earlier, allows remote attackers to affect availability via unknown vectors related to Server Locking.
