Security Advisory Subject: Linux: imlib processes untrusted images Advisory number: CSSA-2002-019.0 Issue date: 2002 April 29 Cross reference: ______________________________________________________________________________ 1. Problem Description Imlib versions prior to 1.9.13 would fall back to loading images via the NetPBM package. NetPBM has various problems itself that make it unsuitable for loading untrusted images. This may allow attackers to construct images that, when loaded by a viewer using Imlib, could cause crashes or potentially, the execution of arbitrary code. In addition, this version (1.9.14) also includes some further fixes from the imlib team. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to imlib-1.9.14-1.i386.rpm prior to imlib-devel-1.9.14-1.i386.rpm OpenLinux 3.1.1 Workstation prior to imlib-1.9.14-1.i386.rpm prior to imlib-devel-1.9.14-1.i386.rpm OpenLinux 3.1 Server prior to imlib-1.9.14-1.i386.rpm prior to imlib-devel-1.9.14-1.i386.rpm OpenLinux 3.1 Workstation prior to imlib-1.9.14-1.i386.rpm prior to imlib-devel-1.9.14-1.i386.rpm 3. Solution The proper solution is to install the latest packages. 4.
