An updated enscript package that fixes several security issues is now available.
GNU enscript converts ASCII files to PostScript.
Enscript has the ability to interpret special escape sequences. A flaw was found in the handling of the epsf command used to insert inline EPS files into a document. An attacker could create a carefully crafted ASCII file which made use of the epsf pipe command in such a way that it could execute arbitrary commands if the file was opened with enscript by a victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1184 to this issue.
Additional flaws in Enscript were also discovered which can only be triggered by executing enscript with carefully crafted command line arguments. These flaws therefore only have a security impact if enscript is executed by other programs and passed untrusted data from remote users. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2004-1185 and CVE-2004-1186 to these issues.
All users of enscript should upgrade to these updated packages, which resolve these issues.
