The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6736-1 advisory.

    It was discovered that zlib, vendored in klibc, incorrectly handled pointer arithmetic. An attacker could     use this issue to cause klibc to crash or to possibly execute arbitrary code. (CVE-2016-9840,     CVE-2016-9841)

    Danilo Ramos discovered that zlib, vendored in klibc, incorrectly handled memory when performing certain     deflating operations. An attacker could use this issue to cause klibc to crash or to possibly execute     arbitrary code. (CVE-2018-25032)

    Evgeny Legerov discovered that zlib, vendored in klibc, incorrectly handled memory when performing certain     inflate operations. An attacker could use this issue to cause klibc to crash or to possibly execute     arbitrary code. (CVE-2022-37434)

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.
