CVE-2022-0529 An issue was found in Unzip's conversion of wide strings to local strings. This could lead to out-of-bounds write attacks.

An attacker can create a zip file that contains a malicious wide string, leading to the crash of an application using the Unzip function. Unzip is used to unzip a compressed file and extract its contents. The vulnerability can be exploited when a user unzips a compressed file.

In order to exploit the vulnerability, an attacker needs to find a way to convince a user to open a malicious file. In most cases, an attacker can send a user a link that contains a malicious file. To avoid such an attack, users should not open links in emails, chats, or social media. Moreover, users should always verify the origin of links before opening them.

Red Hat has released Unzip 6.0, which addresses this vulnerability. The latest update is available for Red Hat Enterprise Linux 6 and 7, Red Hat Enterprise Linux 5, and Red Hat Enterprise Linux 4.
