Debian Security Advisory

xpdf -- local exploit

Date Reported:

10 Sep 2000

Affected Packages:

xpdf

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2000-0727, CVE-2000-0728.

More information:

xpdf as distributed in Debian GNU/Linux 2.2 suffered from two problems:

creation of temporary files was not done safely which made xpdf vulnerable to a symlink attack.
when handling URLs in documents no checking was done for shell metacharacters before starting the browser. This makes it possible to construct a document which cause xpdf to run arbitrary commands when the user views a URL.

Both problems have been fixed in version 0.90-7, and we recommend you upgrade your xpdf package immediately.

Fixed in:
