Adobe has patched a total of 36 vulnerabilities in its Acrobat and Reader products and the DNG software development kit (SDK).
In Acrobat and Reader, the company fixed 24 vulnerabilities, including critical use-after-free, buffer error, out-of-bounds write, and heap overflow issues that could lead to arbitrary code execution. Other vulnerabilities rated critical can allow hackers to bypass security features, the vendor said in its advisory.
The security holes rated important can lead to a denial-of-service (DoS) condition or information disclosure. Several researchers have been credited by Adobe for reporting the Acrobat and Reader vulnerabilities.
Two of the flaws were discovered by a researcher from Cisco Talos, which on Tuesday published a blog post detailing the issues. Both vulnerabilities can be exploited for remote code execution by convincing the targeted user to open a specially crafted PDF file with a vulnerable version of Reader.
In the DNG SDK for Windows and macOS, Adobe fixed a dozen vulnerabilities, including four critical heap overflow bugs that can be exploited for code execution, and eight important out-of-bounds read issues that can lead to information disclosure.
“The overflows could lead to code execution, so if you use the DNG format for your digital photography, definitely make sure you are patched,” Trend Micro’s Zero Day Initiative noted in a blog post.
All of the DNG SDK vulnerabilities were reported to Adobe by Mateusz Jurczyk from Google Project Zero.
Adobe says none of the vulnerabilities patched on Tuesday has been exploited in malicious attacks and, based on the priority ratings assigned by the company, it does not expect to see them being exploited too soon.
Microsoft’s May 2020 security updates patch 111 vulnerabilities, including 16 rated critical.
