CVE-2020-3744Network attack vector

Information disclosure via out-of-bounds read

Published Feb 13, 2020 · Updated Aug 4, 2024

Adobe Acrobat and Reader 2019.021.20061 and earlier contain an out-of-bounds read allowing attackers to disclose information via unspecified vectors. Public Adobe and NVD records do not identify the specific component or operation that reads beyond a valid boundary. Required privileges, interaction, and file-processing conditions are not published, so impact is bounded to information disclosure.
