Package : pstotext
Vulnerability : insecure file name quoting
Problem-Type : local(remote)
Debian-specific: no
CVE ID : CVE-2006-5869
Debian Bug : 356988
Brian May discovered that pstotext, a utility to extract plain text from
Postscript and PDF files, performs insufficient quoting of file names,
which allows execution of arbitrary shell commands.
For the stable distribution (sarge) this problem has been fixed in
version 1.9-1sarge2. The build for the mipsel architecture is not yet
available due to technical problems with the build host.
For the upcoming stable distribution (etch) this problem has been
fixed in version 1.9-4.
For the unstable distribution (sid) this problem has been fixed in
version 1.9-4.
We recommend that you upgrade your pstotext package.
