Summary: thunderbird vulnerabilities

Details: Bob Clary, Christoph Diehl, Christian Holler, Andrew McCreight, Daniel Holbert, Jesse Ruderman, and Randell Jesup discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1952) Nicolas Golubovic discovered that CSP violation reports can be used to overwrite local files. If a user were tricked in to opening a specially crafted website in a browsing context with addon signing disabled and unpacked addons installed, an attacker could potentially exploit this to gain additional privileges. (CVE-2016-1954) Jose Martinez and Romina Santillan discovered a memory leak in libstagefright during MPEG4 video file processing in some circumstances. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via memory exhaustion. (CVE-2016-1957) A use-after-free was discovered in the HTML5 string parser. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1960) A use-after-free was discovered in the SetBody function of HTMLDocument. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1961) Nicolas Grégoire discovered a use-after-free during XML transformations. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1964) A memory corruption issues was discovered in the NPAPI subsystem. If a user were tricked in to opening a specially crafted website in a browsing context with a malicious plugin installed, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1966) Ronald Crane discovered an out-of-bounds read following a failed allocation in the HTML parser in some circumstances. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1974) Francis Gabriel discovered a buffer overflow during ASN.1 decoding in NSS. A remote attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1950) Holger Fuhrmannek, Tyson Smith and Holger Fuhrmannek reported multiple memory safety issues in the Graphite 2 library. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird.
