Discussion

Solaris LBXProxy Display Name Buffer Overflow Vulnerability

Low-Bandwidth X Proxy (lbxproxy) is a server that handles low-bandwidth connections to X Windows. It runs on Solaris as well as a number of Unix and Linux variants.

lbxproxy is prone to a locally exploitable buffer overflow condition. This is due to insufficient bounds checking of the display name command line option.

Successful exploitation will enable an attacker to execute arbitrary attacker-supplied instructions and as a consequence gain elevated privileges.

This issue was reported for lbxproxy on the Sun Solaris operating system. It is not known whether this is an issue on other operating systems.
