Description Josh Bressers 2006-05-03 15:36:46 EDT
Several integer overflow bugs in freetype have been fixed in CVS. The details are below. The descriptions are the CVS commit messages. That patch for each particular comment is keyed off it's # identifier. * Integer overflow #2 * src/bdf/bdflib.c (ERRMSG4): New macro. (_bdf_parse_glyphs): Handle invalid BBX values. * include/freetype/fterrdef.h (FT_Err_Bbx_Too_Big): New error macro. #3 * src/sfnt/ttcmap.c (tt_face_build_cmaps): Handle invalid offset correctly. #4 * src/cff/cfftypes.h (CFF_CharsetRec): Add `max_cid' member. * src/cff/cffload.c (cff_charset_load): Set `charset->max_cid'. * src/cff/cffgload.c (cff_slot_load): Change type of third parameter to `FT_UInt'. Check range of `glyph_index'. * src/cff/cffgload.h: Updated. #6 * src/bdf/bdflib.c: fixed a problem with large encodings. Again, this patch comes from Debian libfreetype6 for 2.1.10 !

Created attachment 128565 [details] Fix for a minor DoS issue Here is a patch for a minor DoS issue as well. It doesn't have a CVE id (it may get one, but probably doesn't deserve one). Please fix it when applying the above patches.

*** Bug 190693 has been marked as a duplicate of this bug. ***
Comment 8 Josh Bressers 2006-05-04 12:44:26 EDT
Bug 190693 has been marked a duplicate of this bug as it contains the patch for additional integer overflows which are covered by CVE-2006-1861. Upstream has fixed a number of potential integer overflows when allocating memory by modifying how memory is now allocated. The patch take from CVS, then clean up is very large. I don't know the source well enough to determine how much of this is needed for our packages. Attachment 128606 [details] is a patch extracted from upstream CVS
Comment 9 Matthew Barnes 2006-05-05 17:30:33 EDT
RHEL 3 and RHEL 4 packages are built, will do RHEL 2.1 next week.
Comment 10 Matthew Barnes 2006-05-10 15:19:10 EDT
RHEL 2.1 packages are built.

Comment 15 Tobias Sandhaas 2006-07-17 05:16:20 EDT
I am eagerly waiting for an advisory and rpm pakets for this (and other) sever issue with freetype. Is there a reason to delay the release?
Comment 16 Mark J. Cox (Product Security) 2006-07-17 10:55:20 EDT
Tobias; updated packages are likely to be pushed this week this week once QA is completed. They were delayed whilst we dealt with other issues that were of a higher security severity.
Comment 17 Mark J. Cox (Product Security) 2006-07-18 05:37:29 EDT
Our maintainer whilst building the packages for CVE-2006-1861 noticed that the upstream patch seemed to be insufficient to correct bad1.pcf from the test suite. He corrected it. Since other vendors have already released updates we need a new CVE name for this issue, CVE-2006-3467. vendor-sec notified yesterday.
