Trustix Secure Linux Security Advisory #2004-0053

Package name:      cyrus-sasl
Summary:           Insecure handling of environment variable
Date:              2004-10-08
Affected versions: Trustix Secure Linux 2.0
                   Trustix Secure Linux 2.1
                   Trustix Operating System - Enterprise Server 2

- --------------------------------------------------------------------------
Package description:
  The cyrus-sasl package contains the Cyrus implementation of SASL.
  SASL is the Simple Authentication and Security Layer, a method for
  adding authentication support to connection-based protocols.

Problem description:
  Kurt Lieber <klieber at gentoo dot org> reported that libsasl honors the
  environment variable SASL_PATH blindly, allowing a local user to compile a
  "library" locally that is executed with the EID of SASL.

  The Common Vulnerabilities and Exposures project (cve.mitre.org) has
  assigned the name CAN-2004-0884 to this issue.
