New zlib packages are available for Slackware 10.0, 10.1, and -current to fix a denial of service security issue. zlib 1.1.x is not affected.

More details about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:


Here are the details from the Slackware 10.1 ChangeLog:

patches/packages/zlib-1.2.2-i486-2.tgz: Patched an overflow in zlib that could cause applications using zlib to crash. The overflow does not involve user supplied data, and therefore does not allow the execution of arbitrary code. However, it could still be used by a remote attacker to create a denial of service. For more information, see: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2096 ( Security fix )
