transmission vulnerabilities
CVE-2009-1757, CVE-2010-0012
===========================================================
It was discovered that the Transmission web interface was vulnerable to cross-site request forgery (CSRF) attacks. If a user were tricked into opening a specially crafted web page in a browser while Transmission was running, an attacker could trigger commands in Transmission. This issue affected Ubuntu 9.04. (CVE-2009-1757)
Dan Rosenberg discovered that Transmission did not properly perform input validation when processing torrent files. If a user were tricked into opening a crafted torrent file, an attacker could overwrite files via directory traversal. (CVE-2010-0012)
The problem can be corrected by upgrading your system to the following package versions:
Ubuntu 8.04 LTS:
transmission-cli 1.06-0ubuntu6.1
transmission-gtk 1.06-0ubuntu6.1
Ubuntu 8.10:
transmission-cli 1.34-0ubuntu2.3
transmission-gtk 1.34-0ubuntu2.3
Ubuntu 9.04:
transmission-cli 1.51-0ubuntu3.1
transmission-gtk 1.51-0ubuntu3.1
Ubuntu 9.10:
transmission-cli 1.75-0ubuntu2.2
transmission-gtk 1.75-0ubuntu2.2
transmission-qt 1.75-0ubuntu2.2
After a standard system upgrade you need to restart Transmission to effect the necessary changes.
Transmission is not the best tool, but if you are going to use it. Atleast install it from the PPA
Add the following lines to your sources.list or in a new file in sources.list.d directory:
deb http://ppa.launchpad.net/transmissionbt/ubuntu [version codename] main
deb-src http://ppa.launchpad.net/transmissionbt/ubuntu [version codename] main
I think they are backporting to Ibex. Just my $0.02
