Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Acrobat Reader versions 24.001.30365, 26.001.21651 and earlier are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to disclose sensitive information. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Adobe Acrobat Reader contains an out-of-bounds read vulnerability in versions 24.001.30365, 26.001.21651 and earlier. The vulnerability allows a specially crafted PDF file to trigger an out-of-bounds memory read, potentially exposing sensitive memory contents to an attacker. Exploitation requires user interaction where the victim must open a malicious PDF file.

MitigationUpdate Adobe Acrobat Reader to the latest patched version provided by Adobe. Since exploitation requires user interaction, organizations should consider user awareness training regarding opening untrusted PDF attachments, though the primary remediation is applying the vendor security update.
