The remote service uses an SSL certificate chain that has been signed using a cryptographically weak hashing algorithm (e.g. MD2, MD4, MD5, or SHA1). These signature algorithms are known to be vulnerable to collision attacks. An attacker can exploit this to generate another certificate with the same digital signature, allowing an attacker to masquerade as the affected service.

Note that this plugin reports all SSL certificate chains signed with SHA-1 that expire after January 1, 2017 as vulnerable. This is in accordance with Google's gradual sunsetting of the SHA-1 cryptographic hash algorithm.

Note that certificates in the chain that are contained in the Nessus CA database (known_CA.inc) have been ignored.

This update for subversion to 1.9.7 fixes security issues and bugs.

The following vulnerabilities were fixed :

  - CVE-2017-9800: A remote attacker could have caused svn     clients to execute arbitrary code via specially crafted     URLs in svn:externals and svn:sync-from-url properties.
    (boo#1051362)

  - CVE-2005-4900: SHA-1 collisions may cause repository     inconsistencies (boo#1026936)

The following bugfix changes are included :

  - Add instructions for running svnserve as a user     different from 'svn', and remove sysconfig variables     that are no longer effective with the systemd unit.
    (boo#1049448)
