CVE-2011-1300 3 Google, Microsoft, Mozilla 3 Chrome, Windows, Firefox 2019-07-18 10.0 HIGH N/A
The Program::getActiveUniformMaxLength function in libGLESv2/Program.cpp in libGLESv2.dll in the WebGLES library in Almost Native Graphics Layer Engine (ANGLE), as used in Mozilla Firefox 4.x before 4.0.1 on Windows and in the GPU process in Google Chrome before 10.0.648.205 on Windows, allows remote attackers to execute arbitrary code via unspecified vectors, related to an "off-by-three" error.
CVE-2019-9796 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-06-26 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected.

CVE-2019-9806 1 Mozilla 1 Firefox 2019-04-29 5.0 MEDIUM 7.5 HIGH
A vulnerability exists during authorization prompting for FTP transaction where successive modal prompts are displayed and cannot be immediately dismissed. This allows for a denial of service (DOS) attack. This vulnerability affects Firefox < 66.
