An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption in the handling of CONNECTION_STATE_HEADER. A rogue server could return a malicious frame header that leads to a smaller target_size value than needed. This condition is then carried on to a memcpy function that copies too much data into a heap buffer.

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2020-3949 advisory.

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.

(CVE-2019-18609)

The remote host is affected by the vulnerability described in GLSA-202003-07 (RabbitMQ C client: Arbitrary code execution)

    It was discovered that RabbitMQ C client incorrectly handled certain       inputs.
  Impact :

    A remote attacker, by sending a specially crafted request, could       possibly execute arbitrary code with the privileges of the process or       cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

According to the version of the librabbitmq package installed, the EulerOS installation on the remote host is affected by the following vulnerability :
