The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5497-2 advisory.
An issue was discovered in libjpeg 9a and 9d. The alloc_sarray function in jmemmgr.c allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted file. (CVE-2018-11212)
An issue was discovered in libjpeg 9a. The get_text_gray_row function in rdppm.c allows remote attackers to cause a denial of service (Segmentation fault) via a crafted file. (CVE-2018-11213)
An issue was discovered in libjpeg 9a. The get_text_rgb_row function in rdppm.c allows remote attackers to cause a denial of service (Segmentation fault) via a crafted file. (CVE-2018-11214)
libjpeg 9c has a large loop because read_pixel in rdtarga.c mishandles EOF. (CVE-2018-11813)
In IJG JPEG (aka libjpeg) before 9d, jpeg_mem_available() in jmemnobs.c in djpeg does not honor the max_memory_to_use setting, possibly causing excessive memory consumption. (CVE-2020-14152)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
