Bug ID: 378535
Summary: Valgrind reports INTERNAL ERROR in execve syscall
wrapper
Product: valgrind
Version: 3.13 SVN
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: iv...@ivosh.net
Target Milestone: ---
Valgrind reports INTERNAL ERROR when a bogus address is passed to execve(argv)
or execve(envp) syscall wrapper.
That's because ML_(pre_argv_envp)() blindly dereferences address passed by the
client program. The syscall wrapper should check at least that the first entry
of argv and envp belongs to a valid client memory segment (there needs to be
always at least one entry for terminating NULL).
