CVE-2008-0420

modules/libpr0n/decoders/bmp/nsBMPDecoder.cpp in Mozilla Firefox before
2.0.0.12, Thunderbird before 2.0.0.12, and SeaMonkey before 1.1.8 does not
properly perform certain calculations related to the mColors table, which
allows remote attackers to read portions of memory uninitialized via a
crafted 8-bit bitmap (BMP) file that triggers an out-of-bounds read within
the heap, as demonstrated using a CANVAS element; or cause a denial of
service (application crash) via a crafted 8-bit bitmap file that triggers
an out-of-bounds read. NOTE: the initial public reports stated that this
affected Firefox in Ubuntu 6.06 through 7.10.
