Description:
A vulnerability has been identified in the 2.4 version of the Linux kernel, which potentially can be exploited by malicious, local users to gain knowledge of sensitive information.

The vulnerability is caused due to an error in the "execve()" system call when handling the file descriptor for the target executable. This has successfully been exploited to read suid executables, where the user only had execute permissions.
