The startauthentication function in lightdm-gtk-greeter.c in LightDM GTK+ Greeter before 1.7.1 does not properly handle the return value from the lightdmgreetergetauthenticationuser function, which allows local users to cause a denial of service (NULL pointer dereference) via an empty username.

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.

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.

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.

The nsGfxScrollFrameInner::IsLTR function in Mozilla Firefox before 26.0, Firefox ESR 24.x before 24.2, Thunderbird before 24.2, and SeaMonkey before 2.23 allows remote attackers to execute arbitrary code via crafted use of JavaScript code for ordered list elements.

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.

Use-after-free vulnerability in Google Chrome before 31.0.1650.48 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the x-webkit-speech attribute in a text INPUT element.

Stefan Esser reported a vulnerability in the PHP openssl extension. A memory corruption flaw was found in the way the opensslx509parse() function of the PHP openssl extension parsed X.509 certificates. A remote attacker could use this flaw to provide a malicious self-signed certificate or a certificate signed by a trusted authority to a PHP application using the aforementioned function, causing the application to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the user running the PHP interpreter.

Red Hat would like to thank the PHP project for reporting this issue. Upstream acknowledges Stefan Esser as the original reporter of this issue.

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.

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.

Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114. CVE-2013-0422 covers both the JMX/MBean and Reflection API issues. NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks. NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11. If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue.

Race condition in PolicyKit (aka polkit) allows local users to bypass intended PolicyKit restrictions and gain privileges by starting a setuid or pkexec process before the authorization check is performed, related to (1) the polkitunixprocessnew API function, (2) the dbus API, or (3) the --process (unix-process) option for authorization to pkcheck.

A denial of service flaw was found in the way the JRE processes XML. A remote attacker could use this flaw to supply crafted XML that would lead to a denial of service.

phpMyAdmin 3.5.x and 4.0.x before 4.0.5 allows remote attackers to bypass the clickjacking protection mechanism via certain vectors related to Header.class.php.

A flaw in certain programs that handle UDP traffic was discovered and assigned the name CVE-1999-0103 (that CVE specifically mentions echo and chargen as vulnerable). In 2002, a Nessus plugin was included [1] that reference this CVE name, but was for the kpasswd service. Until recently, this issue had not been reported upstream. This issue has since been reported upstream [2] and is now fixed [3].

If a malicious remote user were to spoof their IP address to that of another server running kadmind with the password change port (kpasswd, port 464), or to the target server's IP address itself), kpasswd will pass UDP packets to the spoofed address and reply each time. This can be used to consume bandwidth and CPU on the affected servers running kadmind.

This should be fixed in the for krb5-1.11.3 release.

An XML External Entities (XXE) attack was found in the way xmlparse routine, used for producing of xml data type value from character data, of PostgreSQL, an advanced Object-Relational database management system (DBMS), performed parsing of provided character data. An unprivileged database user could issue a specially-crafted SQL query to the PostgreSQL server that, when processed could lead to attacker's ability to read arbitrary system files, accessible with privileges of the user running the PostgreSQL server.
