Name of the Vulnerable Software and Affected Versions Acrobat Reader versions 20.005.30636 through 24.002.20965 and earlier

Description The issue is related to an out-of-bounds read vulnerability in Acrobat Reader when parsing a crafted file, which could result in a read past the end of an allocated memory structure. This could allow an attacker to execute arbitrary code in the context of the current user. Exploitation of this issue requires user interaction, where a victim must open a malicious file.

Recommendations For versions 20.005.30636 through 24.002.20965 and earlier, update to a version that is not affected by this issue to prevent exploitation. As a temporary workaround, consider avoiding the use of crafted files that could trigger the out-of-bounds read vulnerability until a patch is available. Restrict access to untrusted files to minimize the risk of exploitation.
