Adobe Bridge version 11.0.2 (and earlier) is affected by an Access of Uninitialized Pointer vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to disclose arbitrary 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 11.0.2 (y anteriores), está afectada por una vulnerabilidad de variable no inicializada cuando se analiza un archivo especialmente diseñado.
