    A context-dependent attacker may be able to gain escalated privileges,       execute arbitrary code, cause Denial of Service, obtain sensitive       information, or otherwise bypass security restrictions.
  Workaround :

    There are no known workarounds at this time.

New shadow packages are available for Slackware 13.1 and -current to fix a security issue.

Kees Cook discovered that some shadow utilities did not correctly validate user input. A local attacker could exploit this flaw to inject newlines into the /etc/passwd file. If the system was configured to use NIS, this could lead to existing NIS groups or users gaining or losing access to the system, resulting in a denial of service or unauthorized access.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Kees Cook discovered that the chfn and chsh utilities do not properly sanitize user input that includes newlines. An attacker could use this to corrupt passwd entries and may create users or groups in NIS environments.

Packages in the oldstable distribution (lenny) are not affected by this problem.
