Description
FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to version 1.11.0, a STUN packet whose declared attribute length is shorter than the structure the parser casts to causes the parser to read and write past the end of the attribute, producing an out-of-bounds memory access on the per-leg media buffer. This issue has been patched in version 1.11.0.
