Description
This security bulletin contains information about 2 vulnerabilities.
1) Integer underflow (CVE-ID: CVE-2026-44235)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to an integer underflow in AMQP frame length computation in amqp_handle_input() when parsing an undersized AMQP frame. A remote attacker can send a specially crafted undersized AMQP frame to cause a denial of service.
User interaction is required for a victim application to connect to an attacker-controlled AMQP server.
2) Heap-based buffer overflow (CVE-ID: CVE-2026-44236)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to a heap-based buffer overflow in amqp_login_inner() and the outbound frame buffer handling when processing a server-supplied connection.tune frame during the amqp_login() handshake. A remote attacker can send a connection.tune frame with an undersized frame_max value to cause a denial of service.
User interaction is required for a victim application to connect to the malicious AMQP server.
