Subject: [Bug libc/11100] New: sysdeps/unix/sysv/linux/ptrace.c PTRACE_SETOPTIONS inappropriate pointer check
Date: Wed, 16 Dec 2009 22:11:00 -0000 [thread overview]
Message-ID: <20091216221117.11100.chris2k01@hotmail.com> (raw)
In sysdeps/unix/sysv/linux/ptrace.c, on line 102, if __BOUNDED__POINTERS__ is
true, checks are done that pointers point at appropriate locations. Such a
check is done on the "data" argument to ptrace() if the "request" argument is
PTRACE_SETOPTIONS. However, according to ptrace(2) (and, indeed, according to
the gdb sources and the kernel sources), the PTRACE_SETOPTIONS request accepts
a bitmask of PTRACE_O_* values as its "data" argument, *not* a pointer.
