Web11 Apr 2024 · Next stop is CVE-2024-24935, a Microsoft Chromium-based spoofing vulnerability that could potentially allow a threat actor to run malicious scripts on the user’s browser upon interaction with a tainted web server. Once the in-browser script is executed, the user will be redirected to the threat actor-held website. WebThe underlining on line 91 indicates that the value returned by compute_pkgdatadir() is a pointer to some data that is tainted by the environment. The call to strcpy() then copies that data into the local buffer named full_file_name (declared on line 84). This, of course, transfers the taintedness property into that buffer.
