Name of the Vulnerable Software and Affected Versions Adobe Reader versions (affected versions not specified) Adobe Acrobat versions (affected versions not specified)

Description The issue is caused by a buffer overflow in Adobe Reader and Adobe Acrobat, allowing a remote attacker to execute arbitrary code or cause a denial of service (memory corruption) through unknown vectors. It is related to an out-of-bounds read information disclosure vulnerability when parsing font streams in Adobe Reader DC. This can lead to memory corruption, enabling attackers to execute code.

Recommendations For Adobe Reader, update to a version that addresses the buffer overflow issue. For Adobe Acrobat, apply the necessary patch to fix the memory corruption vulnerability. As a temporary workaround, consider restricting the use of Adobe Reader and Adobe Acrobat until a patch is available.
