Updated graphicsmagick packages fix security vulnerability

Publication date: 28 Sep 2016
Modification date: 28 Sep 2016
Type: security
Affected Mageia releases : 5
CVE: CVE-2016-7447 , CVE-2016-7448 , CVE-2016-7449

Description

A possible heap overflow of the EscapeParenthesis() function
(CVE-2016-7447).

The Utah RLE reader did not validate that header information was
reasonable given the file size and so it could cause huge memory
allocations and/or consume huge amounts of CPU (CVE-2016-7448).

The TIFF reader had a bug pertaining to use of TIFFGetField() when a
'count' value is returned.  The bug caused a heap read overflow (due to
using strlcpy() to copy a possibly unterminated string) which could allow
an untrusted file to crash the software (CVE-2016-7449).
