"An update for icoutils is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The icoutils are a set of programs for extracting and converting
images in Microsoft Windows icon and cursor files. These files usually
have the extension .ico or .cur, but they can also be embedded in
executables or libraries.

Security Fix(es) :

* Multiple vulnerabilities were found in icoutils, in the wrestool
program. An attacker could create a crafted executable that, when read
by wrestool, could result in memory corruption leading to a crash or
potential code execution. (CVE-2017-5208, CVE-2017-5333,
CVE-2017-6009)

* A vulnerability was found in icoutils, in the wrestool program. An
attacker could create a crafted executable that, when read by
wrestool, could result in failure to allocate memory or an over-large
memcpy operation, leading to a crash. (CVE-2017-5332)

* Multiple vulnerabilities were found in icoutils, in the icotool
program. An attacker could create a crafted ICO or CUR file that, when
read by icotool, could result in memory corruption leading to a crash
or potential code execution. (CVE-2017-6010, CVE-2017-6011)

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
