:Secunia Research has discovered a vulnerability in CUPS, which can be exploited by malicious people to compromise a vulnerable system.The vulnerability is caused due to a boundary error within the "ippReadIO()" function in cups/ipp.c when processing IPP (Internet Printing Protocol) tags. This can be exploited to overwrite one byte on the stack with a zero by sending an IPP request containing specially crafted "textWithLanguage" or "nameWithLanguage" tags.Successful exploitation allows execution of arbitrary code.The vulnerability is confirmed in version 1.3.3. Other versions may also be affected.Solution:Use CUPS in trusted network environments only.Provided and/or discovered by:Alin Rad Pop, Secunia Research.Original Advisory:Secunia Research:http://secunia.com/secunia_research/2007-76/
