Canonical: >> Ubuntu Linux >> 12.04 Security Vulnerabilities
The HTTP Alternative Services feature in Mozilla Firefox before 37.0.1 allows man-in-the-middle attackers to bypass an intended X.509 certificate-verification step for an SSL server by specifying that server in the uri-host field of an Alt-Svc HTTP/2 response header.

The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.

QEMU, as used in Xen 3.3.x through 4.5.x, does not properly restrict access to PCI command registers, which might allow local HVM guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.

Mozilla Firefox before 37.0 does not require an HTTPS session for lightweight theme add-on installations, which allows man-in-the-middle attackers to bypass an intended user-confirmation requirement by deploying a crafted web site and conducting a DNS spoofing attack against a mozilla.org subdomain.

The QCMS implementation in Mozilla Firefox before 37.0 allows remote attackers to obtain sensitive information from process heap memory or cause a denial of service (out-of-bounds read) via an image that is improperly handled during transformation.

The webrtc::VPMContentAnalysis::Release function in the WebRTC implementation in Mozilla Firefox before 37.0 uses incompatible approaches to the deallocation of memory for simple-type arrays, which might allow remote attackers to cause a denial of service (memory corruption) via unspecified vectors.

The Off Main Thread Compositing (OMTC) implementation in Mozilla Firefox before 37.0 attempts to use memset for a memory region of negative length during interaction with the mozilla::layers::BufferTextureClient::AllocateForSurface function, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors that trigger rendering of 2D graphics content.

The Off Main Thread Compositing (OMTC) implementation in Mozilla Firefox before 37.0 makes an incorrect memset call during interaction with the mozilla::layers::BufferTextureClient::AllocateForSurface function, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors that trigger rendering of 2D graphics content.

The HTMLSourceElement::BindToTree function in Mozilla Firefox before 37.0 does not properly constrain a data type after omitting namespace validation during certain tree-binding operations, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via a crafted HTML document containing a SOURCE element.

The HTMLSourceElement::AfterSetAttr function in Mozilla Firefox before 37.0 does not properly constrain the original data type of a casted value during the setting of a SOURCE element's attributes, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via a crafted HTML document.
