New pcre packages are available for Slackware 12.0, 12.1, and -current to fix a security issue.
More details about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:
Here are the details from the Slackware 12.1 ChangeLog:
patches/packages/pcre-7.7-i486-1_slack12.1.tgz: Upgraded to pcre-7.7. Tavis Ormandy of the Google Security Team found a buffer overflow triggered when handling certain regular expressions. This could lead to a crash or possible execution of code as the user of the PCRE-linked application. For more information, see: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2371 ( Security fix )
Where to find the new packages:
HINT: Getting slow download speeds from ftp.slackware.com? Give slackware.osuosl.org a try. This is another primary FTP site for Slackware that can be considerably faster than downloading directly from ftp.slackware.com.
Thanks to the friendly folks at the OSU Open Source Lab (http://osuosl.org) for donating additional FTP and rsync hosting to the Slackware project! :-)
Also see the "Get Slack" section on http://slackware.com for additional mirror sites near you.
