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.
