- load_image.
-
-We were assuming the input name was well formed, hence was
-nul-terminated. As any data coming from external input, this has to be
-thorougly checked.
-Similar to commit 06d24a79af94837d615d0024916bb95a01bf3c59 but adapted
-to older gimp-2-8 code.

-Subject: [PATCH] Bug 739133 - (CVE-2017-17785) Heap overflow while parsing FLI
- files.
-
-It is possible to trigger a heap overflow while parsing FLI files. The
-RLE decoder is vulnerable to out of boundary writes due to lack of
-boundary checks.
-
-The variable "framebuf" points to a memory area which was allocated
-with fli_header->width * fli_header->height bytes. The RLE decoder
-therefore must never write beyond that limit.
-
-If an illegal frame is detected, the parser won't stop, which means
-that the next valid sequence is properly parsed again. This should
-allow GIMP to parse FLI files as good as possible even if they are
-broken by an attacker or by accident.
-
-While at it, I changed the variable xc to be of type size_t, because
-the multiplication of width and height could overflow a 16 bit type.
-
-Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>

-Be more thorough on valid TGA RGB and RGBA images.
-In particular current TGA plug-in can import RGBA as 32 bits (8 bits per

-RGB as 15 and 24 bits.
-Maybe there exist more variants, but if they do exist, we simply don't

-Subject: [PATCH] newgidmap: enforce setgroups=deny if self-mapping a group
-
-This is necessary to match the kernel-side policy of "self-mapping in a
-user namespace is fine, but you cannot drop groups" -- a policy that was
-created in order to stop user namespaces from allowing trivial privilege
-escalation by dropping supplementary groups that were "blacklisted" from
-certain paths.
-
-This is the simplest fix for the underlying issue, and effectively makes
-it so that unless a user has a valid mapping set in /etc/subgid (which
-only administrators can modify) -- and they are currently trying to use
-that mapping -- then /proc/$pid/setgroups will be set to deny. This
-workaround is only partial, because ideally it should be possible to set
-an "allow_setgroups" or "deny_setgroups" flag in /etc/subgid to allow
-administrators to further restrict newgidmap(1).
-
-We also don't write anything in the "allow" case because "allow" is the
-default, and users may have already written "deny" even if they
-technically are allowed to use setgroups. And we don't write anything if
-the setgroups policy is already "deny".
