Description

The remote OracleVM system is missing necessary patches to address critical security updates :

  • fix heap-based buffer overflow in curl_easy_unescape (CVE-2013-2174)

  • fix cookie tailmatching to prevent cross-domain leakage (CVE-2013-1944)

  • introduce the --delegation option of curl (#746849)

  • fix stack smashing in the FTP implementation (#652557)

  • fix proxy kerberos authentication (#657396)

  • update running_handles counter properly in curl_multi_remove_handle (#688871)

  • add a new option CURLOPT_GSSAPI_DELEGATION (#723643)

  • do not delegate GSSAPI credentials (CVE-2011-2192)

  • avoid use of uninitialized variable on failure of a LDAP request (#655073)

  • proxy tunnel support for LDAP requests (#655073)
