Amazon Linux AMI : GraphicsMagick (ALAS-2016-752)

critical Nessus Plugin ID 94018

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A possible heap overflow was discovered in the EscapeParenthesis() function (CVE-2016-7447).

Various issues were found in the processing of SVG files in GraphicsMagick (CVE-2016-7446).

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).

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, causing a denial of service (CVE-2016-7448)

Solution

Run 'yum update GraphicsMagick' to update your system.
