CVE-2014-0210 [HIGH] CVE-2014-0210: Multiple buffer overflows in X Multiple buffer overflows in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs protocol reply to the (1) _fs_recv_conn_setup, (2) fs_read_open_font, (3) fs_read_query_info, (4) fs_read_extent_info, (5) fs_read_glyphs, (6) fs_read_list, or (7) fs_read_list_info function.

CVE-2014-0209 [MEDIUM] CVE-2014-0209: Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata.

CVE-2013-6462 [CRITICAL] CVE-2013-6462: Stack-based buffer overflow in the bdfReadCharacters function in bitmap/bdfread Stack-based buffer overflow in the bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont 1.1 through 1.4.6 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string in a character name in a BDF font file.

CVE-2011-2895 [HIGH] CVE-2011-2895: The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress 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

CVE-2008-0006 [HIGH] CVE-2008-0006: Buffer overflow in (1) X Buffer overflow in (1) X.Org Xserver before 1.4.1, and (2) the libfont and libXfont libraries on some platforms including Sun Solaris, allows context-dependent attackers to execute arbitrary code via a PCF font with a large difference between the last col and first col values in the PCF_BDF_ENCODINGS table.

CVE-2007-1351 [HIGH] CWE-189 CVE-2007-1351: Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 2007040 Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow.

CVE-2007-1352 [LOW] CVE-2007-1352: Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote a Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow.

CVE-2006-3740 [HIGH] CVE-2006-3740: Integer overflow in the scan_cidfont function in X Integer overflow in the scan_cidfont function in X.Org 6.8.2 and XFree86 X server allows local users to execute arbitrary code via crafted (1) CMap and (2) CIDFont font data with modified item counts in the (a) begincodespacerange, (b) cidrange, and (c) notdefrange sections.
