[DSA071] DSA-071-1 fetchmail |

DSA-071-1 fetchmail Detailed Explanation for this Vulnerability Assessment Salvatore Sanfilippo found two remotely exploitable problems in fetchmail while doing a security audit. In both the IMAP code and the POP3 code, the input isn't verified even though it's used to store a number in an array. Since no bounds checking is done this can be used by a possible hacker to write arbitrary data in memory. A possible hacker can use this if they can get a user to transfer mail from a custom IMAP or POP3 server they control. This has been fixed in version 5.3.3-3, we recommend that you update your fetchmail packages immediately.
