It was discovered that the Avatar upload feature of FUD Forum, a component
of the web based groupware system phpgroupware, does not sufficiently
validate uploaded files, which might lead to the execution of injected web
script code.
For the old stable distribution (woody) this problem has been fixed in
version 0.9.14-0.RC3.2.woody6.
For the stable distribution (sarge) this problem has been fixed in
version 0.9.16.005-3.sarge5.
For the unstable distribution (sid) this problem has been fixed in
version 0.9.16.009-1.
We recommend that you upgrade your phpgroupware packages.
