Secure testing team - Apr 2008 - Bug#475736: tss: local root exploit

Package: tss
Version: 0.8.1-3
Severity: critical
Tags: security
Justification: root security hole

tss has a setuid binary. The source code is src/main.c:

sprintf(glob_string, "%s/.tss/*", getenv("HOME"));

(before dropping setuid, needless to say)
