Detail

Updated freetype2 packages fix security vulnerabilities:

The tt_sbit_decoder_load_image function in sfnt/ttsbit.c in FreeType before 2.5.4 does not properly check for an integer overflow, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted OpenType font (CVE-2014-9656).

The tt_face_load_hdmx function in truetype/ttpload.c in FreeType before 2.5.4 does not establish a minimum record size, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font (CVE-2014-9657).

The tt_face_load_kern function in sfnt/ttkern.c in FreeType before 2.5.4 enforces an incorrect minimum table length, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font (CVE-2014-9658).

The _bdf_parse_glyphs function in bdf/bdflib.c in FreeType before 2.5.4 does not properly handle a missing ENDCHAR record, which allows remote attackers to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted BDF font (CVE-2014-9660).

type42/t42parse.c in FreeType before 2.5.4 does not consider that scanning can be incomplete without triggering an error, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted Type42 font (CVE-2014-9661).

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 allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted cmap SFNT table (CVE-2014-9663).

FreeType before 2.5.4 does not check for the end of the data during certain parsing actions, which allows 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 (CVE-2014-9664).

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 allows 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 (CVE-2014-9666).

sfnt/ttload.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting the values, which allows 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 (CVE-2014-9667).

Multiple integer overflows in sfnt/ttcmap.c in FreeType before 2.5.4 allow 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 (CVE-2014-9669).

Multiple integer signedness errors in the pcf_get_encodings function in pcf/pcfread.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (integer overflow, NULL pointer dereference, and application crash) via a crafted PCF file that specifies negative values for the first column and first row (CVE-2014-9670).

Off-by-one error in the pcf_get_properties function in pcf/pcfread.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PCF file with a 0xffffffff size value that is improperly incremented (CVE-2014-9671).

Array index error in the parse_fond function in base/ftmac.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (out-of-bounds read) or obtain sensitive information from process memory via a crafted FOND resource in a Mac font file (CVE-2014-9672).

Integer signedness error in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted Mac font (CVE-2014-9673).

The Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.5.4 proceeds with adding to length values without validating the original values, which allows remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact via a crafted Mac font (CVE-2014-9674).

bdf/bdflib.c in FreeType before 2.5.4 identifies property names by only verifying that an initial substring is present, which allows remote attackers to discover heap pointer values and bypass the ASLR protection mechanism via a crafted BDF font (CVE-2014-9675).
