data/libsixel-1.8.6/wic/wic.cc:1253:9: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.

data/libsixel-1.8.6/wic/wic.cc:1254:9: [2] (buffer) sprintf:

vsnprintf. Risk is low because the source has a constant maximum length.

On some systems (though not Linux-based systems) an attempt to free()
results from memalign() may fail. This may, on a few systems, be
exploitable. Also note that memalign() may not check that the boundary
parameter is correct (CWE-676). Use posix_memalign instead (defined in
POSIX's 1003.1d). Don't switch to valloc(); it is marked as obsolete in BSD
4.3, as legacy in SUSv2, and is no longer defined in SUSv3. In some cases,
malloc()'s alignment may be sufficient.
