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. Upgrade Instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
