Bug#559827: CVE-2009-3736 local privilege escalation

[Michael Gilbert]

Package: siproxd
Severity: grave
Tags: security

Hi,

The following CVE (Common Vulnerabilities & Exposures) id was
published for libtool.  I have determined that this package embeds a
vulnerable copy of the libtool source code.  However, since this is a
mass bug filing (due to so many packages embedding libtool), I have not
had time to determine whether the vulnerable code is actually present
in any of the binary packages. Please determine whether this is the
case. If the binary packages are not affected, please feel free to close
the bug with a message containing the details of what you did to check.

CVE-2009-3736[0]:
| ltdl.c in libltdl in GNU Libtool 1.5.x, and 2.2.6 before 2.2.6b,
| attempts to open a .la file in the current working directory, which
| allows local users to gain privileges via a Trojan horse file.

Note that this problem also affects etch and lenny, so if your package
is affected, please coordinate with the security team to release the
DSA for the affected packages.

If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
