According to the versions of the exiv2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • The Exiv2::Jp2Image::readMetadata function in jp2image.cpp in Exiv2 0.26 allows remote attackers to cause a denial of service (excessive memory allocation) via a crafted file.(CVE-2018-4868)

  • CiffDirectory::readDirectory() at crwimage_int.cpp in Exiv2 0.26 has excessive stack consumption due to a recursive function, leading to Denial of service.(CVE-2018-17581)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
