Microsoft Internet Explorer 6, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, as demonstrated by Stephen Fewer as the first of three chained vulnerabilities during a Pwn2Own competition at CanSecWest 2011, aka "Object Management Memory Corruption Vulnerability."

Use-after-free vulnerability in WebKit, as used in Apple Safari before 5.0.5; iOS before 4.3.2 for iPhone, iPod, and iPad; iOS before 4.2.7 for iPhone 4 (CDMA); and possibly other products allows remote attackers to execute arbitrary code by adding children to a WBR tag and then removing the tag, related to text nodes, as demonstrated by Chaouki Bekrar during a Pwn2Own competition at CanSecWest 2011.

Double free vulnerability in IBM WebSphere Application Server (WAS) 6.1.0.x before 6.1.0.35 and 7.x before 7.0.0.15 allows remote backend IIOP servers to cause a denial of service (S0C4 ABEND and storage corruption) by rejecting IIOP requests at opportunistic time instants, as demonstrated by requests associated with an ORB_Request::getACRWorkElementPtr function call.

Use-after-free vulnerability in the HTMLCollection implementation in Google Chrome before 10.0.648.204 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

Use-after-free vulnerability in the frame-loader implementation in Google Chrome before 10.0.648.204 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

The regular-expression functionality in Google Chrome before 10.0.648.127 does not properly implement reentrancy, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

Use-after-free vulnerability in Google Chrome before 10.0.648.127 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to "document script lifetime handling."

Use-after-free vulnerability in Google Chrome before 10.0.648.127 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the handling of DOM URLs.

Google Chrome before 10.0.648.127 does not properly handle counter nodes, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

tcptls.c in the TCP/TLS server in Asterisk Open Source 1.6.1.x before 1.6.1.23, 1.6.2.x before 1.6.2.17.1, and 1.8.x before 1.8.3.1 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) by establishing many short TCP sessions to services that use a certain TLS API.

Multiple format string vulnerabilities in phar_object.c in the phar extension in PHP 5.3.5 and earlier allow context-dependent attackers to obtain sensitive information from process memory, cause a denial of service (memory corruption), or possibly execute arbitrary code via format string specifiers in an argument to a class method, leading to an incorrect zend_throw_exception_ex call.

Use-after-free vulnerability in the substr_replace function in PHP 5.3.6 and earlier allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact by using the same variable for multiple arguments.

epan/dissectors/packet-ntlmssp.c in the NTLMSSP dissector in Wireshark before 1.4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted .pcap file.

Use-after-free vulnerability in Google Chrome before 9.0.597.107 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to blocked plug-ins.

rsync 3.x before 3.0.8, when certain recursion, deletion, and ownership options are used, allows remote rsync servers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via malformed data.

libymsg.c in the Yahoo! protocol plugin in libpurple in Pidgin 2.6.0 through 2.7.10 allows (1) remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via a malformed YMSG notification packet, and allows (2) remote Yahoo! servers to cause a denial of service (NULL pointer dereference and application crash) via a malformed YMSG SMS message.

Heap-based buffer overflow in the ldm_frag_add function in fs/partitions/ldm.c in the Linux kernel 2.6.37.2 and earlier might allow local users to gain privileges or obtain sensitive information via a crafted LDM partition table.

Samba 3.x before 3.3.15, 3.4.x before 3.4.12, and 3.5.x before 3.5.7 does not perform range checks for file descriptors before use of the FD_SET macro, which allows remote attackers to cause a denial of service (stack memory corruption, and infinite loop or daemon crash) by opening a large number of files, related to (1) Winbind or (2) smbd.

The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion before 1.6.16, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a request that contains a lock token.

The _zip_name_locate function in zip_name_locate.c in the Zip extension in PHP before 5.3.6 does not properly handle a ZIPARCHIVE::FL_UNCHANGED argument, which might allow context-dependent attackers to cause a denial of service (NULL pointer dereference) via an empty ZIP archive that is processed with a (1) locateName or (2) statName operation.

Use-after-free vulnerability in the addOSPLext method in the Honeywell ScanServer ActiveX control 780.0.20.5 allows remote attackers to execute arbitrary code via a crafted HTML document.
