Last modified
CVE-2010-2089 is a vulnerability of currently unknown severity. The audioop module in Python 2.7 and 3.2 does not verify the relationships between size arguments and byte string lengths, which allows context-dependent attackers to cause a denial of service (memory corruption and application crash) via crafted arguments, as demonstrated by a call to audioop.reverse with a one-byte string, a different vulnerability than CVE-2010-1634.. EPSS estimates a 14.64% chance of exploitation in the next 30 days.
