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 remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - David Koblas' GIF decoder LZW decoder buffer overflow (CVE-2011-2896)

  - pl: buffer overflows in path canonisation and expansion of file names with long paths (CVE-2012-6090)

  - 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 has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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).
