NULL pointer crashes hashname()

От
Bernd Helmle
Дата:
By accidently passing a NULL pointer in a RuleStmt's RangeVar relname i 
recognized
that this can lead to a crash of the backend in the function hashname(), 
located in hashfunc.c. It calls strlen() without checking the key pointer 
in line 126, which leads on my machine to a null pointer violation. Since 
i'm bloody new to the backend i don't really know if its worth to talk 
about, but i want you to know.....

Platform is MDK Linux 10.0 Community Edition, glibc 2.3.3

This is your bug, not hashname's.
