Background ========== PyCrypto is the Python Cryptography Toolkit. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-python/pycrypto < 2.0.1-r8 >= 2.0.1-r8 Description =========== Mike Wiacek of the Google Security Team reported a buffer overflow in the ARC2 module when processing a large ARC2 key length. Impact ====== A remote attacker could entice a user or automated system to decrypt an ARC2 stream in an application using PyCrypto, possibly resulting in the execution of arbitrary code or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All PyCrypto users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/pycrypto-2.0.1-r8" References ========== [ 1 ] CVE-2009-0544 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0544 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200903-11.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
