{"id":"AZL-113365","summary":"CVE-2026-59986 affecting package librabbitmq 0.14.0-1","details":"rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to version 0.17.0, the bounds check (*offset = o + len) \u003c= encoded.len overflows when o + len \u003e SIZE_MAX on 32-bit systems. len is a uint32_t read from the AMQP wire as a BYTES/UTF8 field length. The overflow wraps the check to a small value that passes, producing a decoded amqp_bytes_t with a multi-GB .len pointing into a small frame buffer. This results in an out-of-bounds read of up to ~4GB of process memory on 32-bit systems (ARM, MIPS, x86 ILP32, embedded IoT AMQP clients). Enabling information disclosure or denial of service. Not exploitable on 64-bit systems where size_t is 64-bit. This issue has been patched in version 0.17.0.","modified":"2026-11-13T14:17:22.757757933Z","published":"2026-11-10T17:17:45Z","upstream":["CVE-2026-59986"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59986"}],"affected":[{"package":{"name":"librabbitmq","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/librabbitmq"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"0.14.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-113365.json"}}],"schema_version":"1.9.2"}
