FreeBSD : RabbitMQ-C -- integer overflow leads to heap corruption (7c555ce3-658d-4589-83dd-4b6a31c5d610)

critical Nessus Plugin ID 151120

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

alanxz reports :

When parsing a frame header, validate that the frame_size is less than or equal to INT32_MAX. Given frame_max is limited between 0 and INT32_MAX in amqp_login and friends, this does not change the API.
This prevents a potential buffer overflow when a malicious client sends a frame_size that is close to UINT32_MAX, in which causes an overflow when computing state->target_size resulting in a small value there. A buffer is then allocated with the small amount, then memcopy copies the frame_size writing to memory beyond the end of the buffer.

Solution

Update the affected packages.
