3. Description:

FreeType is a free, high-quality, portable font engine that can open and
manage font files. It also loads, hints, and renders individual glyphs
efficiently.

Multiple integer overflow flaws and an integer signedness flaw, leading to
heap-based buffer overflows, were found in the way FreeType handled Mac
fonts. If a specially crafted font file was loaded by an application linked
against FreeType, it could cause the application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2014-9673, CVE-2014-9674)

Multiple flaws were found in the way FreeType handled fonts in various
formats. If a specially crafted font file was loaded by an application
linked against FreeType, it could cause the application to crash or,
possibly, disclose a portion of the application memory. (CVE-2014-9657,
CVE-2014-9658, CVE-2014-9660, CVE-2014-9661, CVE-2014-9663, CVE-2014-9664,
CVE-2014-9667, CVE-2014-9669, CVE-2014-9670, CVE-2014-9671, CVE-2014-9675)

All freetype users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The X server must be
restarted (log out, then log back in) for this update to take effect.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

3. Description:

The unzip utility is used to list, test, or extract files from a
zip archive.

A buffer overflow was found in the way unzip uncompressed certain extra
fields of a file. A specially crafted Zip archive could cause unzip to
crash or, possibly, execute arbitrary code when the archive was tested with
unzip's '-t' option. (CVE-2014-9636)

A buffer overflow flaw was found in the way unzip computed the CRC32
checksum of certain extra fields of a file. A specially crafted Zip archive
could cause unzip to crash when the archive was tested with unzip's '-t'
option. (CVE-2014-8139)

An integer underflow flaw, leading to a buffer overflow, was found in the
way unzip uncompressed certain extra fields of a file. A specially crafted
Zip archive could cause unzip to crash when the archive was tested with
unzip's '-t' option. (CVE-2014-8140)

A buffer overflow flaw was found in the way unzip handled Zip64 files.
A specially crafted Zip archive could possibly cause unzip to crash when
the archive was uncompressed. (CVE-2014-8141)

Red Hat would like to thank oCERT for reporting the CVE-2014-8139,
CVE-2014-8140, and CVE-2014-8141 issues. oCERT acknowledges Michele
Spagnuolo of the Google Security Team as the original reporter of
these issues.

All unzip users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
