Background
Icoutils is a set of programs that deal with MS Windows icons and cursors. It allows users to extract resources such as icons and cursors from MS Windows executable and library files using the wrestool tool. These resources can then be manipulated or analyzed as needed.
Vulnerability Detail
Three buffer overflow vulnerabilities have been discovered in icoutils:
- CVE-2017-6009: A buffer overflow in wrestool
- CVE-2017-6010: A buffer overflow in the extract_icons function
- CVE-2017-6011: An out-of-bounds read leading to a buffer overflow in icotool
These vulnerabilities can be exploited by processing corrupted ico files, resulting in crashes or potentially allowing attackers to execute arbitrary code. The vulnerabilities pose a risk to systems that use icoutils to handle MS Windows icons and cursors.

FAQ
Icoutils is a collection of programs used to handle MS Windows icons and cursors. It allows users to extract and manipulate these resources from executable and library files.
A buffer overflow vulnerability occurs when a program writes data beyond the boundaries of a buffer, potentially overwriting adjacent memory and leading to crashes or the execution of arbitrary code.
These vulnerabilities can be exploited by processing corrupted ico files using icoutils. Attackers can craft malicious files that trigger buffer overflows, potentially leading to crashes or the execution of arbitrary code.
The impact of these vulnerabilities can range from crashes and denial of service to the execution of arbitrary code. Attackers may be able to take control of affected systems or cause disruption to services that rely on icoutils.
To protect your system, it is crucial to upgrade the icoutils package to the fixed version (0.29.1-5deb7u2 or later). Regularly applying security updates and practicing good security hygiene, such as avoiding processing untrusted files, can also help mitigate the risk.
