Title
Adobe Bridge Out-of-bounds read could lead to Arbitrary Code Execution
Summary
Adobe Bridge version 11.1.1 (and earlier) is affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Severity ?
