According to the versions of the perl-DBD-MySQL package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
The DBD::mysql module before 4.039 for Perl, when using server-side prepared statement support, allows attackers to cause a denial of service (out-of-bounds read) via vectors involving an unaligned number of placeholders in WHERE condition and output fields in SELECT expression.(CVE-2016-1249)
The DBD::mysql module through 4.043 for Perl uses the mysql_ssl=1 setting to mean that SSL is optional (even though this setting’s documentation has a ‘your communication with the server will be encrypted’ statement), which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, a related issue to CVE-2015-3152.(CVE-2017-10789)
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.
