| | | | | | | | | | | | | | | | | | | | | | | | | | | These are paranoid about integer overflow, and will return -1 if their operation would overflow a (signed) integer or if either argument is negative. Note that RenderLarge requests are sized with a uint32_t so in principle this could be sketchy there, but dix limits bigreqs to 128M so you shouldn't ever notice, and honestly if you're sending more than 2G of rendering commands you're already doing something very wrong. v2: Use INT_MAX for consistency with the rest of the server (jcristau) v3: Reject negative arguments (anholt) v4: RHEL5: add limits.h, use inline v5: backport to nx-libs 3.6.x (Mike DePaulo) Reviewed-by: Keith Packard <keithp@keithp.com> Reviewed-by: Julien Cristau <jcristau@debian.org> Reviewed-by: Michal Srb <msrb@suse.com> Reviewed-by: Andy Ritger <aritger@nvidia.com> Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Signed-off-by: Fedora X Ninjas <x@fedoraproject.org> Signed-off-by: Dave Airlie <airlied@redhat.com>

* glx: Be more strict about rejecting invalid image sizes [CVE-2014-8093 2/6]Adam Jackson2015-02-142-14/+14
| | | | | | | | | | | | | | | | | | Before this we'd just clamp the image size to 0, which was just hideously stupid; if the parameters were such that they'd overflow an integer, you'd allocate a small buffer, then pass huge values into (say) ReadPixels, and now you're scribbling over arbitrary server memory. v2: backport to nx-libs 3.6.x (Mike DePaulo) Reviewed-by: Keith Packard <keithp@keithp.com> Reviewed-by: Julien Cristau <jcristau@debian.org> Reviewed-by: Michal Srb <msrb@suse.com> Reviewed-by: Andy Ritger <aritger@nvidia.com> Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Signed-off-by: Fedora X Ninjas <x@fedoraproject.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
* glx: Be more paranoid about variable-length requests [CVE-2014-8093 1/6] (v2)Adam Jackson2015-02-142-4/+4
| | | | | | | | | | | | | | | | | | | | | If the size computation routine returns -1 we should just reject the request outright. Clamping it to zero could give an attacker the opportunity to also mangle cmdlen in such a way that the subsequent length check passes, and the request would get executed, thus passing data we wanted to reject to the renderer. v3: backport to nx-libs 3.6.x (Mike DePaulo) v2: backport to RHEL5 - fix swap paths Reviewed-by: Keith Packard <keithp@keithp.com> Reviewed-by: Julien Cristau <jcristau@debian.org> Reviewed-by: Michal Srb <msrb@suse.com> Reviewed-by: Andy Ritger <aritger@nvidia.com> Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Signed-off-by: Fedora X Ninjas <x@fedoraproject.org> Signed-off-by: Dave Airlie <airlied@redhat.com> fixup swaps
