OTR developers report:

-
The otrl_base64_otr_decode() function and similar functions within OTR - suffer from buffer overflows in the case of malformed input; - specifically if a message of the format of "?OTR:===." is received - then a zero-byte allocation is performed without a similar correlation - between the subsequent base64 decoding write, as such it becomes - possible to write between zero and three bytes incorrectly to the - heap, albeit only with a value of '='.
-
Because this code path is highly utilized, specifically in the - reception of instant messages over pidgin or similar, this - vulnerability is considered severe even though in many platforms and - circumstances the bug would yield an unexploitable state and result - simply in denial of service.
-
The developers of OTR promptly fixed the errors and users of OTR are - advised to upgrade the software at the next release cycle.
