Name of the Vulnerable Software and Affected Versions Adobe Bridge version 11.1.1 and earlier Adobe Prelude versions 10.1 and earlier

Description The issue is related to improper input validation and a Null pointer dereference vulnerability when parsing specially crafted files. An unauthenticated attacker could leverage this vulnerability to achieve an application denial-of-service or execute arbitrary code in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file.

Recommendations For Adobe Bridge version 11.1.1 and earlier, update to a version that addresses the Null pointer dereference vulnerability. For Adobe Prelude versions 10.1 and earlier, update to a version that addresses the improper input validation vulnerability in the XDCAMSAM directory. As a temporary workaround, consider restricting the opening of files from untrusted sources to minimize the risk of exploitation.
