CVE-2017-8105

FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.c.

FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.c.

FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.c.

It was discovered that a heap-based buffer overflow existed in the FreeType library. If a user were tricked into using a specially crafted font file, a remote attacker could cause FreeType to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2016-10328).

FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.c (CVE-2017-8105).

FreeType 2 before 2017-03-26 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_builder_close_contour function in psaux/psobjs.c (CVE-2017-8287).

These are all security issues fixed in the freetype2-devel-2.11.0-1.2 package on the GA media of openSUSE Tumbleweed.

This update for freetype2 fixes the following security issues:

• CVE-2016-10244: Make sure that the parse_charstrings function in type1/t1load.c does ensure that a font contains a glyph name to prevent a DoS through a heap-based buffer over-read or possibly have unspecified other impact via a crafted file (bsc#1028103)
• CVE-2017-8105: Fix an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.ca (bsc#1035807)
• CVE-2017-8287: an out-of-bounds write caused by a heap-based buffer overflow related to the t1_builder_close_contour function in psaux/psobjs.c (bsc#1036457)
• Fix several integer overflow issues in truetype/ttinterp.c (bsc#1079600)

This update for freetype2 fixes the following issues:

Security issue fixed:

• CVE-2016-10244: The parse_charstrings function in type1/t1load.c did not ensure that a font contains a glyph name, which allowed remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted file (bsc#1028103).

• CVE-2017-8105: Fixed an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.ca (bsc#1035807)

• CVE-2017-8287: an out-of-bounds write caused by a heap-based buffer overflow related to the t1_builder_close_contour function in psaux/psobjs.c (bsc#1036457)

This update for freetype2 fixes the following issues:

Update to 2.13.2:

• Some fields in the FT_Outline structure have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input.
• Rare double-free crashes in the cache subsystem have been fixed.
• Excessive stack allocation in the autohinter has been fixed.
• The B/W rasterizer has received a major upkeep that results in large performance improvements. The rendering speed has increased and even doubled for very complex glyphs.

It was 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, resulting in a denial of service, or possibly execute arbitrary code.
