3. Description:

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)
