Description Arvid Requate

2016-02-01 11:52:55 CET

Multiple bugs in processing font files allow denial of service or the execution of arbitrary code:

Debian package version 2.4.9-1.1+deb7u2 fixes:

* remote denial of service (infinite loop) via a "broken number-with-base" in a Postscript stream (CVE-2014-9745)
* use of uninitialized data (CVE-2014-9746)
* t42parse.c vulnerability (CVE-2014-9747)

Debian package version 2.4.9-1.1+deb7u3 fixes

* 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)

Comment 1 Arvid Requate

Upstream Debian package version 2.4.9-1.1+deb7u4 fixes this issue:

* The parse_charstrings function in type1/t1load.c in FreeType 2 before 2.7 does not ensure that a font contains a glyph name, which allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted file. (CVE-2016-10244)

Comment 4 Arvid Requate

Upstream Debian package version 2.4.9-1.1+deb7u5 additionally fixes:

* out-of-bounds write caused by a heap-based buffer overflow related to the cff_parser_run function in cff/cffparse.c. (CVE-2016-10328)

Package imported and built, advisory updated.
