Attackers can send zero-length or 1-3 byte data payloads through a hostile implant session to trigger an out-of-bounds slice access in the vendored Binject library's BinaryMagic function, which propagates unrecovered through the operator gRPC interceptor chain and terminates the server process, affecting all connected operators.","cvssScore":5.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/h00die/sliver_1.7.7_DoS","tags":[]},{"url":"https://www.vulncheck.com/advisories/sliver-denial-of-service-via-pe-parser-slice-bounds-in-operator-rpc","tags":[]}],"exploitRefs":[{"url":"https://github.com/h00die/sliver_1.7.7_DoS","tags":[]}],"hasPoc":true,"ai":null}
