attacker could possibly use this issue to cause a denial of service,
expose sensitive information or execute arbitrary code. This issue only
affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.

could lead to an intentional assertion failure when processing certain
crafted DWARF files. An attacker could possibly use this issue to cause a
denial of service. This issue only affected Ubuntu 20.04 LTS
