Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Adobe Acrobat and Reader versions 2018.011.20038 and earlier, 2017.011.30079 and earlier, and 2015.006.30417 and earlier contain a double-free vulnerability tracked as CVE-2018-4990 and CWE-415. The flaw is a memory-management error that arises during handling of certain PDF documents and carries a CVSS 3.1 base score of 8.8.

An unauthenticated attacker can trigger the issue over the network by supplying a malicious PDF that a user opens in the affected application. Successful exploitation grants arbitrary code execution in the context of the current user, with high impact to confidentiality, integrity, and availability.

Adobe’s security bulletin APSB18-09, referenced at https://helpx.adobe.com/security/products/acrobat/apsb18-09.html, addresses the vulnerability through updated releases and recommends that organizations apply the patches for the supported branches as soon as possible.
