Integer underflow in the pixmantrapezoidvalid macro in pixman.h in Pixman before 0.32.0, as used in X.Org server and cairo, allows context-dependent attackers to cause a denial of service (crash) via a negative bottom value.

The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification (CURLOPTSSLVERIFYPEER), also disables the CURLOPTSSLVERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks.

Mozilla Firefox before 26.0 and SeaMonkey before 2.23 on Linux allow user-assisted remote attackers to read clipboard data by leveraging certain middle-click paste operations.

Mozilla Firefox before 26.0, Firefox ESR 24.x before 24.2, Thunderbird before 24.2, and SeaMonkey before 2.23 do not recognize a user's removal of trust from an EV X.509 certificate, which makes it easier for man-in-the-middle attackers to spoof SSL servers in opportunistic circumstances via a valid certificate that is unacceptable to the user.

The scan function in ext/date/lib/parseisointervals.c in PHP through 5.5.6 does not properly restrict creation of DateInterval objects, which might allow remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted interval specification.

maas-import-pxe-files in MAAS before 13.10 does not verify the integrity of downloaded files, which allows remote attackers to modify these files via a man-in-the-middle (MITM) attack.

Multiple cross-site scripting (XSS) vulnerabilities in OpenStack Dashboard (Horizon) 2013.2 and earlier allow local users to inject arbitrary web script or HTML via an instance name to (1) "Volumes" or (2) "Network Topology" page.

It was reported [1],[2] that libjpeg and libjpeg-turbo would use uninitialized memory when decoding images with missing SOS data for the luminance component (Y) in the presence of valid chroma data (Cr, Cb). An example proof of concept that can be viewed in a browser is also available [3].

This was reported and fixed initially in Google Chrome/Chromium; it does not appear to be fixed in upstream libjpeg or libjpeg-turbo yet. Patches to the third party source in Chromium for libjpeg [4] and libjpeg-turbo [5] however are available.

dbus/SoftwarePropertiesDBus.py in Software Properties 0.92.17 before 0.92.17.3, 0.92.9 before 0.92.9.3, and 0.82.7 before 0.82.7.5 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

ubuntu-system-service 0.2.4 before 0.2.4.1. 0.2.3 before 0.2.3.1, and 0.2.2 before 0.2.2.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

language-selector 0.110.x before 0.110.1, 0.90.x before 0.90.1, and 0.79.x before 0.79.4 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

An integer overflow flaw was found in the way samba read an EA list provided by the client. A malicious client could send a specially crafted EA list that wraps perfectly on a 32-bit boundary, causing the server to loop and re-process the list. This can cause Denial of Service via memory exhaustion.

Format string vulnerability in the b43requestfirmware function in drivers/net/wireless/b43/main.c in the Broadcom B43 wireless driver in the Linux kernel through 3.9.4 allows local users to gain privileges by leveraging root access and including format string specifiers in an fwpostfix modprobe parameter, leading to improper construction of an error message.

telepathy-idle before 0.1.15 does not verify (1) that the issuer is a trusted CA, (2) that the server hostname matches a domain name in the subject's Common Name (CN), or (3) the expiration date of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 do not properly initialize data structures for the nsDOMSVGZoomEvent::mPreviousScale and nsDOMSVGZoomEvent::mNewScale functions, which allows remote attackers to obtain sensitive information from process memory via a crafted web site.

A new attack was discovered against TLS that allows an attacker to recover a limited amount of plaintext from a TLS connection when RC4 encryption is used. The attacks arise from statistical flaws in the keystream generated by the RC4 algorithm which become apparent in TLS ciphertexts when the same plaintext is repeatedly encrypted at a fixed location across many TLS sessions.
