Name of the Vulnerable Software and Affected Versions
The product name cannot be determined (affected versions not specified)
Description
The ELF image activator cleared per-process ASLR (Address Space Layout Randomization, a security technique that randomizes memory addresses to prevent exploitation) preference flags for setuid binaries after the PIE (Position Independent Executable) base address was computed. This sequence allowed a user-requested ASLR disable to remain active during the base address selection. An unprivileged local user can disable ASLR for a setuid PIE binary by calling the
procctl(2) function before execve(2), which simplifies the exploitation of other memory corruption issues within that binary.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
