Description Jan Lieskovsky 2013-02-11 13:33:16 UTC
A stack-based buffer overflow flaw was found in the way Transmission, a free, lightweight BitTorrent client, performed connection acknowledgements processing. A remote attacker could issue a specially-crafted request that, when processed would lead to transmission-daemon crash.

Comment 1 Jan Lieskovsky 2013-02-11 13:40:17 UTC
This issue did NOT affect the versions of the transmission package, as shipped with Fedora release of 17 and 18 (they contain 2.76 upstream based versions already, which is not vulnerable to this problem any more).


This issue affects the version of the transmission package, as shipped with Fedora release of 16. Please schedule an update.


This issue did NOT affect the versions of the transmission package, as shipped with Fedora EPEL 5 and Fedora EPEL 6 (they don't contain the relevant code part yet).
