Description

This security bulletin contains information about 7 vulnerabilities.


1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-68060)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 improper handling of type size/count values in amqp 1.0 protocol handling when processing crafted pre-authentication input. A remote attacker can send crafted data to trigger excessive allocation and cause a denial of service.


2) Stack-based buffer overflow (CVE-ID: CVE-2026-68073)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 stack-based buffer overflow in the AMQP 1.0 protocol plugin when processing nested type data. A remote attacker can send specially crafted nested type data to cause a denial of service.

The issue can be triggered before authentication.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-68074)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 unbounded symbol value caching in the amqp 1.0 protocol plugin when processing pre-authentication input. A remote attacker can send specially crafted protocol data to cause a denial of service.


4) Resource exhaustion (CVE-ID: CVE-2026-68075)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to improper resource control in the amqp 1.0 protocol plugin session flow control handling when processing incoming session flow control windows. A remote user can exceed the incoming session flow control window to cause a denial of service.


5) Input validation error (CVE-ID: CVE-2026-68077)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to improper input validation in disposition frame handling when processing crafted disposition frames with large or illegal ranges. A remote user can send a specially crafted disposition frame to cause a denial of service.


6) Resource exhaustion (CVE-ID: CVE-2026-68078)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to improper resource management in the amqp 1.0 protocol plugin when handling incoming deliveries with excessive transfer frames. A remote user can send a large number of transfer frames in an incoming delivery to cause a denial of service.


7) Resource exhaustion (CVE-ID: CVE-2026-68080)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to improper resource control in the amqp 1.0 protocol plugin when processing echo flow responses. A remote user can send echo flow messages to cause a denial of service.
