NLSCCSTR.DLL in the web service in IBM Lotus Domino Server 6.5.1, 6.0.3, and possibly other versions allows remote attackers to cause a denial of service (deep recursion and nHTTP.exe process crash) via a long GET request containing UNICODE decimal value 430 characters, which causes the stack to be exhausted. NOTE: IBM has reported that it is unable to replicate this issue.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
