Description
The issue is related to an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. This vulnerability can be exploited by an attacker to bypass mitigations such as ASLR. Exploitation requires user interaction, where a victim must open a malicious file. The vulnerability is also associated with the processing of embedded fonts, which can allow an attacker to gain unauthorized access to protected information.
Recommendations
For Adobe Acrobat Reader versions 23.003.20244 and earlier, update to a version later than 23.003.20244 to resolve the issue.
For Adobe Acrobat Reader versions 20.005.30467 and earlier, update to a version later than 20.005.30467 to resolve the issue.
As a temporary workaround, consider avoiding the use of embedded fonts in PDF files until a patch is available.
Restrict access to malicious PDF files to minimize the risk of exploitation.
