Descriptions

Adobe Framemaker versions 2019 Update 8 (and earlier) and 2020 Release Update 2 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious TIF file.

Adobe Framemaker versiones 2019 Update 8 (y anteriores), y 2020 Release Update 2 (y anteriores), están afectadas por una vulnerabilidad de lectura fuera de límites que podría conllevar a una divulgación de memoria confidencial. Un atacante podría aprovechar esta vulnerabilidad para omitir mitigaciones como ASLR. Es requerida una interacción del usuario para explotar este problema, ya que la víctima debe abrir un archivo TIF malicioso

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Adobe FrameMaker. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the processing of TIF images. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
