Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-aeb75f8b5b advisory.

- An out-of-bounds read flaw was found in w3m, in the Strnew_size function in Str.c. This issue may allow an attacker to cause a denial of service through a crafted HTML file. (CVE-2023-38252)

- An out-of-bounds read flaw was found in w3m, in the growbuf_to_Str function in indep.c. This issue may allow an attacker to cause a denial of service through a crafted HTML file. (CVE-2023-38253)

- An out-of-bounds write issue has been discovered in the backspace handling of the checkType() function in etc.c within the W3M application. This vulnerability is triggered by supplying a specially crafted HTML file to the w3m binary. Exploitation of this flaw could lead to application crashes, resulting in a denial of service condition. (CVE-2023-4255)

- There is an out-of-bounds write in checkType located in etc.c in w3m 0.5.3. It can be triggered by sending a crafted HTML file to the w3m binary. It allows an attacker to cause Denial of Service or possibly have unspecified other impact. (CVE-2022-38223)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected w3m package.
