CVE-2021-40750
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdobe Bridge version 11.1.1 (and earlier) is affected by a Null pointer dereference vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to achieve an application denial-of-service in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAdobe Bridge versions 11.1.1 and earlier contain a null pointer dereference vulnerability triggered when parsing a specially crafted malicious file. An attacker can cause the application to crash by convincing a user to open the crafted file, resulting in a denial-of-service condition.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Adobe Bridge installationCheck if Adobe Bridge is installed on the system. On Windows, look in Program Files/Adobe. On macOS, check the Applications folder for Adobe Bridge.Affected if Adobe Bridge is present on the system and the installed version is 11.1.1 or earlier
-
Identify installed Adobe Bridge versionLaunch Adobe Bridge and navigate to Help > About Adobe Bridge. Note the version number displayed in the About dialog.Affected if The displayed version is 11.1.1 or any version number lower than 11.1.1
-
Verify version against affected rangeCompare the identified version to the affected range: any version 11.1.1 or earlier is vulnerable. Versions after 11.1.1 are not affected.Affected if The installed version falls within the range of 11.1.1 or earlier
The environment is affected if Adobe Bridge version 11.1.1 or earlier is installed, as this version range contains the null pointer dereference vulnerability triggered by specially crafted files
