Use after free in Proxy in Google Chrome prior to 148.0.7778.216 allowed a remote attacker to execute arbitrary code via a crafted PAC script. (Chromium security severity: Critical)
Weakness
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
