Ubuntu Linux 8.10 Description:

Ubuntu has issued an update for python-crypto. This fixes a vulnerability, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the "block_init()" function in src/ARC2.c when processing key data. This can be exploited to cause a buffer overflow by initializing ARC2 with a key longer than 128 bytes. Secunia advisories - http://secunia.com/advisories/34147/
