SUSE-SA:2003:0010: libmcrypt |

Check for the version of the libmcrypt package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory SUSE-SA:2003:0010 (libmcrypt). Libmcrypt is a data encryption library that is able to load crypto- modules at run-time by using libltdl. Versions of libmcrypt prior to 2.5.5 include several buffer overflows that can be triggered by passing very long input to the mcrypt_* functions. The way libmcrypt handles dynamic crypto-modules via libltdl leads to memory-leaks that can cause a Denial-of-Service condition. This Problem can just be solved by linking modules static. This security update does not solve the memory-leak problem to avoid compatibility problems. Future releases of libmcrypt will be linked statically. To add the new library to the shared library cache you have to run ldconfig(8) as root. Additionally every program that is linked with libmcrypt needs to be restarted. ldd(1) can be used to find out which libraries are used by a program. Another way to acertain which process uses a shared library that had been deleted is: lsof -n 2>/dev/null | grep RPMDELETE | cut -d ' ' -f 1 | sort | uniq There is no temporary fix known. Please install the new packages from our FTP servers. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command 'rpm -Fhv file.rpm' to apply the update.
