Multiple stack-based buffer overflows in the canoniseFileName function in os/pl-os.c in SWI-Prolog before 6.2.5 and 6.3.x before 6.3.7 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted filename.

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

  - Multiple stack-based buffer overflows in the canoniseFileName function in os/pl-os.c in SWI-Prolog before     6.2.5 and 6.3.x before 6.3.7 allow remote attackers to cause a denial of service (application crash) or     possibly execute arbitrary code via a crafted filename. (CVE-2012-6089)

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

The remote host is affected by the vulnerability described in GLSA-201312-05 (SWI-Prolog : Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in SWI-Prolog:
      * An error in the canoniseFileName() function could cause a stack-based       buffer overflow (CVE-2012-6089).
      * An error in the expand() function could cause a stack-based buffer       overflow (CVE-2012-6090).
  Impact :

    A context-dependent attack can create files with specially crafted       names, causing arbitrary code execution or a denial of service condition.
  Workaround :

    There is no known workaround at this time.

Fix two buffer overflows when expanding file name glob (CVE-2012-6090) and when canonizing path (CVE-2012-6089).
