Cross-site scripting (XSS) vulnerability in index.php in AppServ Open Project 2.5.10 and earlier allows remote attackers to inject arbitrary web script or HTML via the appservlang parameter.

Unspecified vulnerability in appserv/main.php in AppServ 2.4.5 allows remote attackers to include arbitrary files via the appserv_root parameter. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information. There is not enough detail from these third party sources to know whether this is directory traversal, remote file include, or another issue.

The f2 shell script in the f2c package 3.1 allows local users to read arbitrary files via a symlink attack on temporary files.

AppServ 2.5.x and earlier installs a default username and password, which allows remote attackers to gain access.

Open Projects Network Internet Relay Chat (IRC) daemon u2.10.05.18 does not perform a double-reverse DNS lookup, which allows remote attackers to spoof any valid hostname on the Internet. NOTE: a followup post suggests that this is not an issue in the daemon.

libX11 X library allows remote attackers to cause a denial of service via a resource mask of 0, which causes libX11 to go into an infinite loop.

libICE in XFree86 allows remote attackers to cause a denial of service by specifying a large value which is not properly checked by the SKIP_STRING macro.
