CVE-2021-21091

Estado: ModificadaBaja (3.3)—

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.

CVSS
