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)

Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update for icoutils to version 0.31.1 fixes the following issues :

  - CVE-2017-5208: An integer overflow allows maliciously     crafted files to cause DoS or code execution     (boo#1018756).

  - CVE-2017-5331: Incorrect out of bounds checks in     check_offset allow for DoS or code execution     (boo#1018756).

  - CVE-2017-5332: Missing out of bounds checks in     extract_group_icon_cursor_resource allow for DoS or code     execution (boo#1018756).

  - CVE-2017-5333: Incorrect out of bounds checks in     check_offset allow for DoS or code execution     (boo#1018756).

It was discovered that icoutils incorrectly handled memory when processing certain files. If a user or automated system were tricked into opening a specially crafted file, an attacker could cause icoutils to crash, resulting in a denial of service, or possibly execute arbitrary code.
