It was discovered that aircrack-ng, a WEP/WPA security analysis tool, performs insufficient validation of 802.11 authentication packets, which allows the execution of arbitrary code.
The oldstable distribution (sarge) doesn't contain aircrack-ng packages.
For the stable distribution (etch) this problem has been fixed in version 0.6.2-7etch1.
For the unstable distribution (sid) this problem has been fixed in version 0.7-3.
We recommend that you upgrade your aircrack-ng packages. Packages for the arm, sparc, mips and mipsel architectures are not yet available. They will be provided later.
