KLA11271 Multiple vulnerabilities in Mozilla Firefox and Mozilla Firefox ESR

Multiple serious vulnerabilities have been found in Mozilla Firefox and Mozilla Firefox ESR. Malicious users can exploit these vulnerabilities to bypass security restrictions, execute arbitrary code, cause denial of service and obtain sensitive information. Below is a complete list of...

Security vulnerabilities fixed in Firefox ESR 60.1 — Mozilla

A buffer overflow can occur when rendering canvas content while adjusting the height and width of the element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash. A use-after-free vulnerability can occur when deleti...
