Package : osh
Vulnerability : programming error
Problem type : local
Debian-specific: no
CVE ID : CVE-2005-3347 CVE-2005-3533
Debian Bug : 338312

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:

CVE-2005-3347

Charles Stevenson discovered a bug in the substitution of
variables that allows a local attacker to open a root shell.

CVE-2005-3533

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.
