"Today in a coordinated effort between all major Linux
vendors, a vulnerability in the zlib library was announced,
potentially affecting every installed Linux system in existance.
The vulnerability is rooted in the free() function and how it
used. Quoting from the EnGarde Secure Linux advisory, "The zlib
shared library may attempt to free() a memory region more then
once, potentially yielding a system exploitable by certain programs
that use it for decompression. Because certain packages include
their own zlib implementation or statically link against the system
zlib, several packages need to be updated to properly fix this
bug."
