Directory traversal vulnerability in Android Crash Reporter in Mozilla Firefox before 28.0 on Android allows attackers to trigger the transmission of local files to arbitrary servers, or cause a denial of service (application crash), via a crafted application that specifies Android Crash Reporter arguments.

Mozilla Firefox before 27.0 on Android 4.2 and earlier creates system-log entries containing profile paths, which allows attackers to obtain sensitive information via a crafted application.

Mozilla Firefox before 27.0 does not properly restrict access to about:home buttons by script on other pages, which allows user-assisted remote attackers to cause a denial of service (session restore) via a crafted web site.

Mozilla Firefox before 26.0 does not properly remove the Application Installation doorhanger, which makes it easier for remote attackers to spoof a Web App installation site by controlling the timing of page navigation.

Integer overflow in the PL_ArenaAllocate function in Mozilla Netscape Portable Runtime (NSPR) before 4.10.2, as used in Firefox before 25.0.1, Firefox ESR 17.x before 17.0.11 and 24.x before 24.1.1, and SeaMonkey before 2.22.1, allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted X.509 certificate, a related issue to CVE-2013-1741.

Use-after-free vulnerability in the nsEventListenerManager::SetEventHandler function in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code via vectors related to a memory allocation through the garbage collection (GC) API.

The cycle collection (CC) implementation in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 does not properly determine the thread for release of an image object, which allows remote attackers to execute arbitrary code or cause a denial of service (race condition and application crash) via a large HTML document containing IMG elements, as demonstrated by the Never-Ending Reddit on reddit.com.

The Worker::SetEventListener function in the Web workers implementation in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to direct proxies.

Use-after-free vulnerability in the nsIPresShell::GetPresContext function in the PresShell (aka presentation shell) implementation in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption and application crash) via vectors involving a CANVAS element, a mozTextStyle attribute, and an onresize event.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
