According to its version, the clamd antivirus daemon on the remote host is earlier than 0.96.5. Such versions are reportedly affected by multiple vulnerabilities :

  - Multiple errors exist in the PDF processing functions in     'libclamav/pdf.c', which could lead to application     crashes. (Bugs 2358, 2380, 2396)

  - An off-by-one error exists in the handling of icons such     that a crafted icon may be used to cause an integer     overflow. (Bug 2344)

The remote host is running a version of Mac OS X 10.5 that does not have Security Update 2011-001 applied. 

This security update contains fixes for the following products :

  - Apache
  - bzip2
  - ClamAV
  - ImageIO
  - Kerberos
  - Libinfo
  - libxml
  - Mailman
  - PHP
  - QuickLook
  - Ruby
  - X11

Multiple vulnerabilities were discovered and corrected in clamav :

Multiple unspecified vulnerabilities in pdf.c in libclamav in ClamAV before 0.96.5 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PDF document (CVE-2010-4260, (CVE-2010-4479).

Off-by-one error in the icon_cb function in pe_icons.c in libclamav in ClamAV before 0.96.5 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors. NOTE: some of these details are obtained from third-party information (CVE-2010-4261).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

The updated clamav packages have been upgraded to the 0.96.5 version that is not vulnerable to these issues.

The remote host is running a version of Mac OS X 10.6.x that is prior to 10.6.7.

Mac OS X 10.6.7 contains security fixes for the following products :

  - AirPort
  - Apache
  - AppleScript
  - ATS
  - bzip2
  - CarbonCore
  - ClamAV
  - CoreText
  - File Quarantine
  - HFS
  - ImageIO
  - Image RAW
  - Installer
  - Kerberos
  - Kernel
  - Libinfo
  - libxml
  - Mailman
  - PHP
  - QuickLook
  - QuickTime
  - Ruby
  - Samba
  - Subversion
  - Terminal
  - X11

Arkadiusz Miskiewicz and others discovered that the PDF processing code in libclamav improperly validated input. This could allow a remote attacker to craft a PDF document that could crash clamav or possibly execute arbitrary code. (CVE-2010-4260, CVE-2010-4479)

It was discovered that an off-by-one error in the icon_cb function in pe_icons.c in libclamav could allow an attacker to corrupt memory, causing clamav to crash or possibly execute arbitrary code.
(CVE-2010-4261)

In the default installation, attackers would be isolated by the clamav AppArmor profile.

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

The remote host is affected by the vulnerability described in GLSA-201110-20 (Clam AntiVirus: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Clam AntiVirus. Please       review the CVE identifiers referenced below for details.
  Impact :

    An unauthenticated remote attacker may execute arbitrary code with the       privileges of the Clam AntiVirus process or cause a Denial of Service by       causing an affected user or system to scan a crafted file.
  Workaround :

    There is no known workaround at this time.
