kernel: exec: Fix ToCToU between perm check and set-uid/gid usage

A vulnerability was found in the Linux kernel. The fix addresses a race condition during file execution exec, where a file’s permissions could change between an initial check and execution, potentially allowing unauthorized privilege escalation. Specifically, a non-privileged user could gain root...

CVE-2024-43882

In the Linux kernel, the following vulnerability has been resolved: exec: Fix ToCToU between perm check and set-uid/gid usage When opening a file for exec via dofilpopen, permission checking is done against the file's metadata at that moment, and on success, a file pointer is passed back. Much...

CVE-2024-43882

CVE-2024-43882 is a Linux kernel race Condition (ToCToU) in exec path: permission checks for a file are done at do_filp_open(), but the metadata (mode/UID/GID) used later in execve() can be changed before execution, enabling potential root privilege escalation. The issue is exploitable in scenari...

Avoiding Death by a Thousand Scripts: Using Automated Content Security Policies

Businesses know they need to secure their client-side scripts. Content security policies CSPs are a great way to do that. But CSPs are cumbersome. One mistake and you have a potentially significant client-side security gap. Finding those gaps means long and tedious hours or days in manual code...
