Subversion svn:// connections, including svn+ssh:// and svn+<custom>://, use a custom network protocol [1] with Lisp-like syntax. The code implementing the protocol has dedicated codepaths for serialization of revision numbers into protocol integers. A particular client query could cause the server to attempt to reply with a revision number whose value is the invalid revision number constant `SVN_INVALID_REVNUM`, thereby triggering an assertion failure in the the serialization layer. |
