[DSA918] DSA-918-1 osh

Vulnerability Assessment Summary
DSA-918-1 osh

Detailed Explanation for this Vulnerability Assessment

Several security related problems have been discovered in osh, the
operator's shell for executing defined programs in a privileged
environment. The Common Vulnerabilities and Exposures project
identifies the following vulnerabilities:
Charles Stevenson discovered a bug in the substitution of
variables that permits a local attacker to open a root shell.
Solar Eclipse discovered a buffer overflow caused by the current
working directory plus a filename that could be used to execute
arbitrary code and e.g. open a root shell.
For the old stable distribution (woody) these problems have been fixed in
version 1.7-11woody2.
For the stable distribution (sarge) these problems have been fixed in
version 1.7-13sarge1.
For the unstable distribution (sid) these problems have been fixed in
version 1.7-15, however, the package has been removed entirely.
We recommend that you upgrade your osh package.
