A programming error exists in a way Randombit Botan cryptographic library version 2.0.1 implements x500 string comparisons which could lead to certificate verification issues and abuse. A specially crafted X509 certificate would need to be delivered to the client or server application in order to trigger this vulnerability.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A programming error exists in a way Randombit Botan cryptographic library version 2.0.1 implements x500     string comparisons which could lead to certificate verification issues and abuse. A specially crafted X509     certificate would need to be delivered to the client or server application in order to trigger this     vulnerability. (CVE-2017-2801)

Note that Nessus relies on the presence of the package as reported by the vendor.

Aleksandar Nikolic discovered that an error in the x509 parser of the Botan crypto library could result in an out-of-bounds memory read, resulting in denial of service or an information leak if processing a malformed certificate.

A bug in X509 DN string comparisons could result in out of bound reads. This could result in information leakage, denial of service, or potentially incorrect certificate validation results.

For Debian 7 'Wheezy', these problems have been fixed in version 1.10.5-1+deb7u3.

We recommend that you upgrade your botan1.10 packages.
