CVE Author: NIST National Vulnerability Database (NVD)

AV:N/AC:L/Au:N/C:P/I:P/A:P

Summary:
The remote host is missing an update for the 'jackson-databind' Linux Distribution Package(s) announced via the DSA-4542-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
It was discovered that jackson-databind, a Java library used to parse JSON and other data formats, did not properly validate user input before attempting deserialization. This allowed an attacker providing maliciously crafted input to perform code execution, or read arbitrary files on the server.

Affected Versions:

Recommendations:
For the oldstable distribution (stretch), these problems have been fixed in version 2.8.6-1+deb9u6. For the stable distribution (buster), these problems have been fixed in version 2.9.8-3+deb10u1. We recommend that you upgrade your jackson-databind Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package
