Analysis

Technical impact

Acrobat Reader is affected by an integer overflow or wraparound vulnerability that could result in arbitrary code execution in the context of the current user. The flaw occurs when processing a maliciously crafted file, and the vulnerability may be triggered when a user opens that file.

Risk and Exploitability

The CVSS score is 7.8, indicating high severity. The EPSS score is not available and the flaw is not listed in the CISA KEV catalog.
