Arch Linux Security Advisory ASA-201609-22 ========================================== Severity: Critical Date : 2016-09-22 CVE-ID : CVE-2016-5256 CVE-2016-5257 CVE-2016-5270 CVE-2016-5271 CVE-2016-5272 CVE-2016-5273 CVE-2016-5274 CVE-2016-5275 CVE-2016-5276 CVE-2016-5277 CVE-2016-5278 CVE-2016-5279 CVE-2016-5280 CVE-2016-5281 CVE-2016-5282 CVE-2016-5283 CVE-2016-5284 Package : firefox Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package firefox before version 49.0-1 is vulnerable to multiple issues including but not limited to arbitrary code execution, information disclosure and certificate verification bypass. Resolution ========== Upgrade to 49.0-1. # pacman -Syu "firefox>=49.0-1" The problems have been fixed upstream in version 49.0. Workaround ========== None. Description =========== - CVE-2016-5256 (arbitrary code execution) Mozilla developers Christoph Diehl, Christian Holler, Gary Kwong, Nathan Froyd, Honza Bambas, Seth Fowler, and Michael Smith reported memory safety bugs present in Firefox 48. Some of these bugs showed evidence of memory corruption under certain circumstances could potentially exploited to run arbitrary code. - CVE-2016-5257 (arbitrary code execution) Mozilla developers and community members Christoph Diehl, Andrew McCreight, Dan Minor, Byron Campen, Jon Coppeard, Steve Fink, Tyson Smith, Philipp, and Carsten Book reported memory safety bugs present in Firefox 48 and Firefox ESR 45.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort at least some of these could be exploited to run arbitrary code. - CVE-2016-5270 (arbitrary code execution) An out-of-bounds write of a boolean value during text conversion with some unicode characters. - CVE-2016-5271 (information disclosure) An out-of-bounds read during the processing of text runs in some pages using display:contents. - CVE-2016-5272 (arbitrary code execution) A bad cast when processing layout with input elements can result in a potentially exploitable crash. - CVE-2016-5273 (arbitrary code execution) A potentially exploitable crash in accessibility in the mozilla::a11y::HyperTextAccessible::GetChildOffset function. - CVE-2016-5274 (arbitrary code execution) A use-after-free vulnerability has been discovered in the nsFrameManager::CaptureFrameState function in web animations during restyling. - CVE-2016-5275 (arbitrary code execution) A buffer overflow vulnerability has been discovered in the mozilla::gfx::FilterSupport::ComputeSourceNeededRegions function when working with empty filters during canvas rendering. - CVE-2016-5276 (arbitrary code execution) A use-after-free vulnerability has been discovered in the mozilla::a11y::DocAccessible::ProcessInvalidationList function triggered by setting a aria-owns attribute. - CVE-2016-5277 (arbitrary code execution) A user-after-free vulnerability has been disconvered in the nsRefreshDriver::Tick function with web animations when destroying a timeline. - CVE-2016-5278 (arbitrary code execution) A potentially exploitable crash caused by a heap based buffer overflow has been discovered in the nsBMPEncoder::AddImageFrame function while encoding image frames to images. - CVE-2016-5279 (information disclosure) The full path to local files is available to scripts when local files are drag and dropped into Firefox. - CVE-2016-5280 (arbitrary code execution) A use-after-free vulnerability has been discovered in the mozilla::nsTextNodeDirectionalityMap::RemoveElementFromMap function when changing text direction. - CVE-2016-5281 (arbitrary code execution) A use-after-free vulnerability has been discovered in the DOMSVGLength when manipulating SVG format content through a script. - CVE-2016-5282 (access restriction bypass) Favicons can be loaded through non-whitelisted protocols, such as jar. - CVE-2016-5283 (information disclosure) A timing attack vulnerability was discovered using iframes to potentially reveal private cross-origin data using document resizes and link colors. - CVE-2016-5284 (certificate verification bypass) Due to flaws in the process used to update "Preloaded Public Key Pinning", the pinning for add-on updates became ineffective in early September. An attacker who was able to get a mis-issued certificate for a Mozilla web site could send malicious add-on updates to users on networks controlled by the attacker. Users who have not installed any add-ons are not affected. Impact ====== A remote attacker is able to execute arbitrary code, disclose sensitive information and bypass certificate verification via various vectors.
