A crafted Connect request causes an out-of-bounds write. This can lead to a crash (denial of service) or potentially arbitrary code execution.\n\n\n\nThis option is disabled by default.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://rt-labs.com/wp-content/uploads/2026/10/RRTL-261019-01.pdf","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
