BitlBee before 3.5 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a file transfer request for a contact that is not in the contact list.

It was discovered that bitlbee, an IRC to other chat networks gateway, contained issues that allowed a remote attacker to cause a denial of service (via application crash), or potentially execute arbitrary commands.

This update for bitlbee fixes the following security issues :

  - A file transfer request from a contact not in the     contact list could have resulted in a NULL pointer     dereference, causing remote DoS by malicious remote     clients (CVE-2016-10189, bnc#1022498).

CVE-2017-5668 Fix for incomplete fix for 'NULL pointer dereference with file transfer request from unknown contacts'. (Though this package wasn't in Wheezy with this issue, I mention it here. The fix was done with the second patch for CVE-2016-10189)

CVE-2016-10189 NULL pointer dereference with file transfer request from unknown contacts.

CVE-2016-10188 deactivate any incoming file transfer for bitlbee This affects any libpurple protocol when used through BitlBee. It does not affect other libpurple-based clients such as pidgin.
