Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2007-5939 unimportant priority: Debian including 1 source packages (heimdal), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The gss_userok function in appl/ftp/ftpd/gss_userok.c in Heimdal 0.7.2 does not allocate memory for the ticketfile pointer before calling free, which allows remote attackers to have an unknown impact via an invalid username. NOTE: the vulnerability was originally reported for ftpd.c, but this is incorrect.
