freetype: postscript type1 font parsing vulnerability

Integer signedness error in psaux/t1decode.c in FreeType before 2.4.6, as used in CoreGraphics in Apple iOS before 4.2.9 and 4.3.x before 4.3.4 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted Type 1 font in a PDF document, as exploited in the wild in July 2011.

BSD compress LZW decoder buffer overflow

The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896.

freetype: heap buffer over-read in BDF parsing _bdf_is_atom() (#35597, #35598)

FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, allows remote attackers to cause a denial of service (invalid heap read operation and memory corruption) or possibly execute arbitrary code via crafted property data in a BDF font.

freetype: NULL dereference in the SHZ instruction implementation in TTF BCI (#35601)

FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, allows remote attackers to cause a denial of service (NULL pointer dereference and memory corruption) or possibly execute arbitrary code via a crafted TrueType font.

freetype: heap off-by-one buffer underflow in Type42 parser t42_parse_sfnts() (#35602)

FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, allows remote attackers to cause a denial of service (invalid heap read operation and memory corruption) or possibly execute arbitrary code via a crafted SFNT string in a Type 42 font.

freetype: heap buffer over-read in PCF parser pcf_get_properties() (#35603)

FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, allows remote attackers to cause a denial of service (invalid heap read operation and memory corruption) or possibly execute arbitrary code via crafted property data in a PCF font.

freetype: incorrect type cast allowing input sanity check bypass in ft_smooth_render_generic() (#35604)

FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, on 64-bit platforms allows remote attackers to cause a denial of service (invalid heap read operation and memory corruption) or possibly execute arbitrary code via vectors related to the cell table of a font.
