These security issues were fixed:

• CVE-2014-9663: The tt_cmap4_validate function in sfnt/ttcmap.c in FreeType before 2.5.4 validates a certain length field before that field's value is completely calculated, which allowed remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted cmap SFNT table (bnc#916865).
• CVE-2014-9662: cff/cf2ft.c in FreeType before 2.5.4 did not validate the return values of point-allocation functions, which allowed remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted OTF font (bnc#916860).
• CVE-2014-9661: type42/t42parse.c in FreeType before 2.5.4 did not consider that scanning can be incomplete without triggering an error, which allowed remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted Type42 font (bnc#916859).
• CVE-2014-9660: The _bdf_parse_glyphs function in bdf/bdflib.c in FreeType before 2.5.4 did not properly handle a missing ENDCHAR record, which allowed remote attackers to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted BDF font (bnc#916858).
• CVE-2014-9667: sfnt/ttload.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting the values, which allowed remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted SFNT table (bnc#916861).
• CVE-2014-9666: The tt_sbit_decoder_init function in sfnt/ttsbit.c in FreeType before 2.5.4 proceeds with a count-to-size association without restricting the count value, which allowed remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted embedded bitmap (bnc#916862).
• CVE-2014-9665: The Load_SBit_Png function in sfnt/pngshim.c in FreeType before 2.5.4 did not restrict the rows and pitch values of PNG data, which allowed remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact by embedding a PNG file in a .ttf font file (bnc#916863).
• CVE-2014-9664: FreeType before 2.5.4 did not check for the end of the data during certain parsing actions, which allowed remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted Type42 font, related to type42/t42parse.c and type1/t1load.c (bnc#916864).
• CVE-2014-9669: Multiple integer overflows in sfnt/ttcmap.c in FreeType before 2.5.4 allowed remote attackers to cause a denial of service (out-of-bounds read or memory corruption) or possibly have unspecified other impact via a crafted cmap SFNT table (bnc#916870).
• CVE-2014-9668: The woff_open_font function in sfnt/sfobjs.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting length values, which allowed remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact via a crafted Web Open Font Format (WOFF) file (bnc#916868).
• CVE-2014-9656: The tt_sbit_decoder_load_image function in sfnt/ttsbit.c in FreeType before 2.5.4 did not properly check for an integer overflow, which allowed remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted OpenType font (bnc#916847).
• CVE-2014-9658: The tt_face_load_kern function in sfnt/ttkern.c in FreeType before 2.5.4 enforces an incorrect minimum table length, which allowed remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font (bnc#916857).
• CVE-2014-9659: cff/cf2intrp.c in the CFF CharString interpreter in FreeType…

cff/cf2intrp.c in the CFF CharString interpreter in FreeType before 2.5.4 proceeds with additional hints after the hint mask has been computed, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted OpenType font. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2240.

Mateusz Jurczyk discovered that FreeType did not correctly handle certain malformed font files. If a user were tricked into using a specially crafted font file, a remote attacker could cause FreeType to crash or possibly execute arbitrary code with user privileges.
