I'm wondering if this should have received a CVE.
https://bugs.gentoo.org/show_bug.cgi?id=377917 quotes upstream:
"This fixes a heap overflow in the parsing of the command line...
this may have security repercussions if
tcptrack is configured as a handler for other applications that can
pass user-supplied command line input to tcptrack."
The "attack" is through a command line argument. While it's listed as a
sniffer, the above text suggests that tcptrack might not be
setuid/privileged, since the only given scenario is "as a handler for
other applications." Unless this is a typical/known scenario, this seems
like just another unprivileged application, in which case the control
over a command line argument would not directly cross privilege
boundaries, thus falling into the realm of "bug" and not "vulnerability."
FWIW, we're treating it as a non-security issue in Debian.
