----------------------------------------------------------------------- Immunix Secured OS Security Advisory Packages updated: LPRng Affected products: Immunix OS 7+ Bugs fixed: CAN-2003-0136 Date: Wed Jun 4 2003 Advisory ID: IMNX-2003-7+-013-01 Author: Seth Arnold <> ----------------------------------------------------------------------- Description: Quoting from the Red Hat security advisory: LPRng is a print spooler. LPRng includes a program, psbanner, that can be used to produce Postscript banner pages to separate print jobs. A vulnerability has been found in psbanner, which creates a temporary file with a known filename in an insecure manner. An attacker could create a symbolic link and cause arbitrary files to be written as the 'lp' user. Our thanks to Karol Lewandowski for discovering this problem. We've also changed ownership of the utility programs from lp:lp to root:root, which should help mitigate the potential problems in the event of future security problems in LPRng.
