Integer overflow in Adobe Flash Player before 18.0.0.324 and 19.x and 20.x before 20.0.0.267 on Windows and OS X and before 11.2.202.559 on Linux, Adobe AIR before 20.0.0.233, Adobe AIR SDK before 20.0.0.233, and Adobe AIR SDK & Compiler before 20.0.0.233 allows attackers to execute arbitrary code via unspecified vectors.
Adobe Flash Player 18.x through 18.0.0.252 and 19.x through 19.0.0.207 on Windows and OS X and 11.x through 11.2.202.535 on Linux allows remote attackers to execute arbitrary code via a crafted SWF file, as exploited in the wild in October 2015.
Moxilla Firefox allows remote attackers to bypass the Same Origin Policy to read arbitrary files or gain privileges.
It was discovered that libtasn1 library function asn1getbitder() could incorrectly report negative bit length of the value read from ASN.1 input. This could possibly lead to an out of bounds access in an application using libtasn1, for example in case if application tried to terminate read value with NUL byte.
The following upstream commit corrects the issue and causes the function to report error rather than return negative length value: http://git.savannah.gnu.org/cgit/libtasn1.git/commit/?id=1c3ccb3e040bf13e342ee60bc23b21b97b11923f
The Web Notification API in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to bypass intended source-component restrictions and execute arbitrary JavaScript code in a privileged context via a crafted web page for which Notification.permission is granted.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Use-after-free vulnerability in the nsGenericHTMLElement::GetWidthHeightForImage function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving an imgLoader object that is not properly handled during an image-resize operation.
The SVG filter implementation in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive displacement-correlation information, and possibly bypass the Same Origin Policy and read text from a different domain, via a timing attack involving feDisplacementMap elements, a related issue to CVE-2013-1693.
The mozilla::WaveReader::DecodeAudioData function in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive information from process heap memory, cause a denial of service (out-of-bounds read and application crash), or possibly have unspecified other impact via a crafted WAV file.
TypedArrayObject.cpp in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 does not prevent a zero-length transition during use of an ArrayBuffer object, which allows remote attackers to execute arbitrary code or cause a denial of service (heap-based out-of-bounds write or read) via a crafted web site.
Buffer overflow in the cairotruetypeindextoucs4 function in cairo, as used in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25, allows remote attackers to execute arbitrary code via a crafted extension that renders fonts in a PDF document.
Adobe Flash Player contains a double free vulnerability that allows a remote attacker to execute arbitrary code.
Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 allow remote attackers to bypass intended restrictions on window objects by leveraging inconsistency in native getter methods across different JavaScript engines.
The Web workers implementation in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 allows remote attackers to bypass the Same Origin Policy and obtain sensitive authentication information via vectors involving error messages.
The System Only Wrapper (SOW) implementation in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 does not prevent certain cloning operations, which allows remote attackers to bypass intended restrictions on XUL content via vectors involving XBL content scopes.
RasterImage.cpp in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 does not prevent access to discarded data, which allows remote attackers to execute arbitrary code or cause a denial of service (incorrect write operations) via crafted image data, as demonstrated by Goo Create.
Buffer overflow in client/mysql.cc in Oracle MySQL and MariaDB before 5.5.35 allows remote database servers to cause a denial of service (crash) and possibly execute arbitrary code via a long server version string.
Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location.
Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space."
Unspecified vulnerability in Adobe Flash Player allows remote attackers to execute arbitrary code or cause a denial of service via crafted SWF content.

Adobe Flash Player contains a memory corruption vulnerability that allows for remote code execution or denial-of-service (DoS).
Sauli Pahlman of CERT-FI provided us with fuzzed PDF file which causes xpdf / poppler PDF parser to crash.
The crash is caused by an attempt to dereference uninitialized Gfx::parser pointer in Gfx::getPos(), which assumes parser is either NULL or valid Parser pointer.

Description of problem: CVE-2009-3553 (bug #530111) has not been completely fixed.
Version-Release number of selected component (if applicable): Versions known to be affected:
cups-1.3.7-11.el54.5 (RHEL-5.4.z) cups-1.3.7-16.el5 (RHEL-5)
Additional info: The cause is that the cupsdDoSelect() function uses one of several implementations depending on the underlying select/poll capabilities of the operating system. For kqueue and epoll implementations, cupsdRemoveSelect() does not immediately decrease the reference count for the file descriptor and instead adds it to the cupsdinactivefds array. File descriptors in that array are finally dereferenced in cupsdStopSelect() (i.e. program termination).
In Red Hat Enterprise Linux, the epoll implementation is used.
The previous fix for CVE-2009-3553 was to check that another reference was held for the file descriptor before calling the writecb function; however, that will always be the case for both the epoll and kqueue implementations.
The correct fix is to check whether the file descriptor is in the cupsdinactivefds array before calling the writecb function.
A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic.
The streamreqbodycl function in modproxyhttp.c in the modproxy module in the Apache HTTP Server before 2.3.3, when a reverse proxy is configured, does not properly handle an amount of streamed data that exceeds the Content-Length value, which allows remote attackers to cause a denial of service (CPU consumption) via crafted requests.
François Guerraz reported in Debian BTS a possible DoS (CPU consumption) a DoS with moddeflate since it does not stop to compress large files even after the network connection has been closed. This allows to use large amounts of CPU if there is a largish file available that has moddeflate enabled.
