CVE-2016-1930

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird (CVE-2016-1930, CVE-2016-1935).

Multiple security flaws were found in the graphite2 font library bundled with Thunderbird. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird (CVE-2016-1521, CVE-2016-1522, CVE-2016-1523, CVE-2016-1526).

Thunderbird includes a bundled copy of the graphite2 library, which has been updated in Thunderbird 38.6.0.

These are all security issues fixed in the MozillaFirefox-50.1.0-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the MozillaThunderbird-45.5.1-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the firefox-esr-128.5.1-1.1 package on the GA media of openSUSE Tumbleweed.

Bob Clary, Christian Holler, Nils Ohlmeier, Gary Kwong, Jesse Ruderman, Carsten Book, Randell Jesup, Nicolas Pierron, Eric Rescorla, Tyson Smith, and Gabor Krizsanits discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, 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 Firefox. (CVE-2016-1930, CVE-2016-1931)

Gustavo Grieco discovered an out-of-memory crash when loading GIF images in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could exploit this to cause a denial of service. (CVE-2016-1933)

Aki Helin discovered a buffer overflow when rendering WebGL content in some circumstances. If a user were tricked in to opening a specially crafted website, 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 Firefox. (CVE-2016-1935)

It was discovered that a delay was missing when focusing the protocol handler dialog. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to conduct clickjacking attacks. (CVE-2016-1937)

Hanno Böck discovered that calculations with mp_div and mp_exptmod in NSS produce incorrect results in some circumstances, resulting in cryptographic weaknesses. (CVE-2016-1938)

Nicholas Hurley discovered that Firefox allows for control characters to be set in cookie names. An attacker could potentially exploit this to conduct cookie injection attacks on some web servers. (CVE-2016-1939)

It was discovered that when certain invalid URLs are pasted in to the addressbar, the addressbar contents may be manipulated to show the location of arbitrary websites. An attacker could potentially exploit this to conduct URL spoofing attacks. (CVE-2016-1942)

Ronald Crane discovered three vulnerabilities through code inspection. If a user were tricked in to opening a specially crafted website, 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 Firefox. (CVE-2016-1944, CVE-2016-1945, CVE-2016-1946)

François Marier discovered that Application Reputation lookups didn't work correctly, disabling warnings for potentially malicious downloads. An attacker could potentially exploit this by tricking a user in to downloading a malicious file. Other parts of the Safe Browsing feature were unaffected by this. (CVE-2016-1947)

Karthikeyan Bhargavan and Gaetan Leurent discovered that NSS incorrectly allowed MD5 to be used for TLS 1.2 connections. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to view sensitive information. (CVE-2015-7575)

Yves Younan discovered that graphite2 incorrectly handled certain malformed fonts. If a user were tricked into 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 arbitary code with the privileges of the user invoking Thunderbird.
