Description

According to its version, the ClamAV clamd antivirus daemon on the remote host is prior to 0.98.5. It is, therefore, potentially affected by the following vulnerabilities :

  • An error exists related to using the 'clamscan -a' command to scan certain JavaScript files that could cause the application to crash. (CVE-2013-6497)

  • Errors exist related to scanning maliciously crafted Yoda's Crypter files that could cause a heap-based buffer overflow or an application crash. (CVE-2014-9050)
