Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS : Qt vulnerabilities (USN-8076-1)

critical Nessus Plugin ID 301536

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8076-1 advisory.

 It was discovered that Qt did not correctly handle OpenSSL's error queue. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 20.04 LTS.
 (CVE-2020-13962)

 It was discovered that Qt incorrectly handled certain XBM image files. If a user or automated system were tricked into opening a specially crafted PPM file, a remote attacker could cause Qt to crash, resulting in a denial of service. This issue was only addressed in Ubuntu 16.04 LTS and Ubuntu 20.04 LTS.
 (CVE-2020-17507)

 It was discovered that Qt did not correctly handle executing specific binaries. If a user or automated system were tricked into executing a binary at a specific file path, an attacker could cause a denial of service or execute arbitrary code. This issue was only addressed in Ubuntu 20.04 LTS. (CVE-2022-25255)

 It was discovered that Qt did not correctly handle certain integer arithmetic. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-51714)

 It was discovered that Qt did not correctly handle certain encrypted connections. An attacker could possibly use this issue to leak sensitive information. This issue was only addressed in Ubuntu 24.04 LTS.
 (CVE-2024-39936)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 packages.
