Description Janek Walkenhorst

2015-05-06 16:32:54 CEST

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

CVE-2014-9674:

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.

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)
