It was discovered that Qt incorrectly handled certain PPM images. 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 only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-19872)

It was discovered that Qt incorrectly handled certain text files. If a user or automated system were tricked into opening a specially crafted text file, a remote attacker could cause Qt to crash, resulting in a denial of service. This issue only affected Ubuntu 19.10. (CVE-2019-18281)

It was discovered that Qt incorrectly searched for plugins in the current working directory. An attacker could possibly use this issue to execute arbitrary code. (CVE-2020-0569)

It was discovered that Qt incorrectly searched for libraries relative to the current working directory. An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 19.10. (CVE-2020-0570)
