The FS_CheckFilenameIsNotExecutable function in qcommon/files.c in the ioQuake3 engine 1.36 and earlier, as used in World of Padman, Smokin' Guns, OpenArena, Tremulous, and ioUrbanTerror, does not properly determine dangerous file extensions, which allows remote attackers to execute arbitrary code via a crafted third-party addon that creates a Trojan horse DLL file.

The remote host is affected by the vulnerability described in GLSA-201706-23 (Urban Terror: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Urban Terror. Please       review the CVE identifiers referenced below for details.
  Impact :

  Workaround :

    There is no known workaround at this time.

- Update to 1.36 svn snapshot r2102

    - This fixes 2 security issues where a malicious server       could execute arbitrary code on connecting clients       (rhbz#725951) :
