Positive Technologies (AI Summary)

CVSS v3.1

9.8

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions OpenSSL versions prior to 1.1.0

Description The issue is related to the BN bn2dec function in the crypto/bn/bn print.c file of the OpenSSL library, which does not properly validate division results. This allows remote attackers to cause a denial of service, such as an out-of-bounds write and application crash, or possibly have other unspecified impacts via unknown vectors.

Recommendations For versions prior to 1.1.0, update to version 1.1.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the BN bn2dec function until a patch is available.
