This vulnerability occurs because of computation that reads data that is past the end of the target buffer. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.","published":"2018-01-09T21:29:01.000Z","lastModified":"2026-06-17T01:59:12.000Z","status":"Modified","sourceIdentifier":"psirt@adobe.com","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-125"],"affected":["redhat/enterprise linux desktop","redhat/enterprise linux server","redhat/enterprise linux workstation","adobe/flash player"],"epss":{"score":0.05509,"percentile":0.92755,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (5.51%).
