Title: WMCube/GDK Object File Buffer Overflow Vulnerability
Severity: MODERATE
Description:
WMCube/GDK is a freely available, open source application for monitoring CPU load. It can be used with one, or multiple CPU's.
A problem with WMCube/GDK could make it possible for a local user to gain elevated privileges. The problem is in the handling of object files.
WMCube/GDK allows the loading of object files by executing users. A user may specify their own object file to be loaded by the program using the -o flag.
WMCube/GDK does not properly impose the limit of 64 byte object files hard-coded into the program. Because of this, it is possible for a local user to load an object file greater than 64 bytes, creating a buffer overflow. This overflow could be used to overwrite stack variables, including the return address, and execute arbitrary code.
A local attacker may gain egid 'kmem', which allows for reading of kernel memory. Elevation to root is imminent when attackers can read kmem.
Affected Products:
- Timecop WMCube/GDK 0.98.0
