Quote:Adobe on Tuesday released patches for Acrobat and Reader, Flash Player, ColdFusion and Creative Cloud. One of the Reader flaws is a critical data leakage issue whose details were made public by a researcher in January.

The company has resolved a total of 71 vulnerabilities in Acrobat and Reader products. One of them has been described as an information disclosure problem that can lead to sensitive data getting leaked.

The flaw was detailed in a blog post published in late January by researcher Alex Inführ, who showed how it can be exploited by a specially crafted PDF document to send SMB requests to the attacker’s server when the file is opened.

The vulnerability is similar to CVE-2018-4993, which Adobe patched last year. It allows a remote attacker to steal a user’s NTLM hash included in an SMB request, and it can be leveraged to alert an attacker when their malicious PDF document has been opened by the targeted user.
