Frank Mcingvale » Luxman : Security Vulnerabilities, CVEs,

Buffer overflow in luxman before 0.41, if used with certain insecure svgalib libraries, allows local users to execute arbitrary code via a long -f command line argument.

Maped in LuxMan 0.41 uses the user-provided search path to find and execute the gzip program, which allows local users to modify /dev/mem and gain privileges via a modified PATH environment variable that points to a Trojan horse gzip program.
