On Tuesday, Mozilla and Google announced the availability of stable updates for Firefox and Chrome that fix a number of serious security flaws, including memory corruption problems.
Four of the seven ‘high severity’ vulnerabilities, which are described as memory corruption bugs affecting the browser’s IPC components, were fixed in Firefox 117, which was made available by Mozilla.
The first three flaws, tracked as CVE-2023-4573, CVE-2023-4574, and CVE-2023-4575 and reported by the same security researcher (also known as sonakkbi), “could have led to a use-after-free causing a potentially exploitable crash,” according to Mozilla’s advisory.
The fourth flaw, identified as CVE-2023-4577, might have caused a crash that could have been used for malicious purposes.
