The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5407-1 advisory.
Integer overflow in the write_png function in cairo 1.14.6 allows remote attackers to cause a denial of service (invalid pointer dereference) via a large svg file. (CVE-2016-9082)
cairo-truetype-subset.c in cairo 1.15.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) because of mishandling of an unexpected malloc(0) call. (CVE-2017-9814)
An issue was discovered in cairo 1.16.0. There is an infinite loop in the function _arc_error_normalized in the file cairo-arc.c, related to _arc_max_angle_for_tolerance_normalized. (CVE-2019-6462)
A flaw was found in cairo’s image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo’s image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-35492)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
