Description Tomas Hoger 2009-05-05 14:18:32 UTC
A stack-based buffer overflow existed in cscope's putstring function in cscope's versions prior to 15.6.  A long function or symbol name in source code file could result in cscope crash or code execution when searching the source code for any function or symbol name.

Issue was originally reported via bug #189666, it can be reproduced using memcheck/tests/match-overrun.c from valgrind source tarball.

In cscope 15.6, putstring was replaced with function fetch_string_from_dbase, which accepts target buffer size as its argument.
