Descriptions
Adobe Bridge versions 10.1.1 (and earlier) and 11.0.1 (and earlier) are affected by an Out-of-bounds read vulnerability when parsing a crafted file. An unauthenticated attacker could leverage this vulnerability to disclose sensitive memory information in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Adobe Bridge versiones 10.1.1 (y anteriores) y versiones 11.0.1 (y anteriores) están afectadas por una vulnerabilidad de lectura fuera de límites cuando analiza un archivo diseñado. Un atacante no autenticado podría aprovechar esta vulnerabilidad para revelar información confidencial de la memoria en el contexto del usuario actual. Es requerida una interacción del usuario para explotar este problema, ya que la víctima debe abrir un archivo malicioso
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Adobe Bridge. 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 parsing of HEIC files. 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 structure. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
