Package        : enscript
Vulnerability  : several
Problem-Type   : local (remote)
Debian-specific: no
CVE ID         : CAN-2004-1184 CAN-2004-1185 CAN-2004-1186

Erik Sjölund has discovered several security relevant problems in
enscript, a program to convert ASCII text into Postscript and other
formats.  The Common Vulnerabilities and Exposures project identifies
the following vulnerabilities:

CAN-2004-1184

    Unsanitised input can cause the execution of arbitrary commands
    via EPSF pipe support.  This has been disabled, also upstream.
    
CAN-2004-1185

    Due to missing sanitising of filenames it is possible that a
    specially crafted filename can cause arbitrary commands to be
    executed.

CAN-2004-1186

    Multiple buffer overflows can cause the program to crash.

Usually, enscript is only run locally, but since it is executed inside
of viewcvs some of the problems mentioned above can easily be turned
into a remote vulnerability.

For the stable distribution (woody) these problems have been fixed in
version 1.6.3-1.3.

For the unstable distribution (sid) these problems have been fixed in
version 1.6.4-6.

We recommend that you upgrade your enscript package.
