MGASA-2019-0194 - Updated graphicsmagick packages fix security vulnerabilities
Publication date: 21 Jun 2019
URL: https://advisories.mageia.org/MGASA-2019-0194.html
Type: security
Affected Mageia releases: 6
GraphicsMagick 1.3.32 is now released, fixing another 52 additional
issues detected by oss-fuzz.
Of special mention is a bug reported to us by "Battle Furry" via our
security mail alias. This bug (was considered to be a "feature")
allows including file text as rendered text on a graphic image, or as
text hidden in metadata, by using a file refered to with '@...ename'
syntax where text to be rendered normally appears. This issue was
inherited from ImageMagick 5.5.2 and it even appears in ImageMagick
4.2.9.
It has been determined that the SVG and WMF formats may be used to
supply this '@...ename' syntax, resulting in rendered text on a
graphic image, or as text hidden in metadata (e.g. the image comment).
Furthermore, it may be that other applications and web sites accept
text to be rendered on behalf of users and that this issue could allow
untrusted users to receive content considered to be secure and private
(e.g. private keys or passwords).
