2018-07-16Prevent OOB access on illegal server response.Tobias Stoeckmann
While parsing Xorg responses it is possible to trigger an out of boundary read if the response does not contain enough bytes. In case of IPv4, the padding normally prevents this, but IPv6 addresses can trigger an out of boundary read. It takes a hostile xorg-server to reproduce this issue. If os/access.c is adjusted to always use a length of 1, it is possible to reproduce it and make it visible with an ASAN-compiled xhost. Reading past the memory boundary could reveal sensitive information to external DNS servers, because a lookup will be performed.

2013-02-28Drop pre-POSIX signal handling support in favor of sigaction()Alan Coopersmith
X_NOT_POSIX has never been defined by our autoconf scripts, only for a few platforms in <X11/Xosdefs.h>, of which MinGW seems to be the most relevant today, and since that doesn't have alarm() it doesn't need this code either. First pass was done with 'unifdef -UX_NOT_POSIX', followed by manual tweaking to adjust indent levels, etc. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Jon TURNEY <jon.turney@dronecode.org.uk>
