The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2024:3066 advisory.

  • Buffer Overflow vulnerability in function ID3_Support::ID3v2Frame::getFrameValue in exempi 2.5.0 and earlier allows remote attackers to cause a denial of service via opening of crafted audio file with ID3V2 frame. (CVE-2020-18651)

  • Buffer Overflow vulnerability in WEBP_Support.cpp in exempi 2.5.0 and earlier allows remote attackers to cause a denial of service via opening of crafted webp file. (CVE-2020-18652)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
