    CVE-2007-3996

    Summary: Integer overflows in libgd (before 2.0.35) in gdImageCreate, gdImageCreateTrueColor and gdImageCopyResized on large width/height, overflowing the pixel-buffer allocation. The libgd 2.0.35 fix — the overflow2() helper and its guards on the sx*sy allocations — is already present in this trixie source: overflow2() is defined in src/extra/gd/gdhelpers.c and gdImageCreate / gdImageCreateTrueColor in src/extra/gd/gd.c bail out via overflow2(sx, sy) and the per-row size checks before allocating. There is nothing to backport; the vulnerability does not reproduce against 0.2.13. Debian rates trixie "unimportant".
