Is this vulnerability in other versions of Enterprise server? Does it exist on all platforms? Is this an issue only with the SSL server (SSL Handshake? huh? what does THAT have to do with a GET request?) or does this affect the entire server? Are patches available for previous versions of Enterprise server? > Additional Information: > > To download the FlexCheck for this vulnerability for Internet Scanner 6.0, > go to the following URL: > > http://download.iss.net/eval/ISNetscapeGetOverflowFlexCheck.exe Oh, so the only way we're going to get anything resembling useful information about wether we're running vulnerable servers is if we run out and get a copy of Internet Scanner? -- Erik Fichtner; Warrior SysAdmin (emf|techs) http://www.obfuscation.org/~techs N 38 53.055' W 77 21.860' 764 ft.
