What is the Zlib Double-Free Vulnerability and Why Should I Care?

Dave Aiello wrote, "Last week, a story made the rounds of a bug in a component of Linux called Zlib. This is a library upon which gzip (GNU zip), a compression utility, is based. Gzip turned out to be much more widely implemented than originally thought, in part because it is implemented without use of any patented compression algorithms."


"It turns out that a number of widely-used Perl modules also use the zlib library. I had no idea what the scope of the effort involved in patching the affected Perl modules would be. So, I posted a question about it on PerlMonks and got some interesting responses. I recommend that developers with Perl code in production read this PerlMonks thread and consider the implications."
