CVE-2021-3449

TITLE

OpenSSL Code problem vulnerability

DESCRIPTION

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). The product supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, secure hash algorithms, etc. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat Advanced Cluster Management for Kubernetes version 2.3 Advisory ID: RHSA-2021:3016-01 Product: Red Hat ACM Advisory URL: https://access.redhat.com/errata/RHSA-2021:3016 Issue date: 2021-08-05 CVE Names: CVE-2016-10228 CVE-2017-14502 CVE-2018-20843 CVE-2018-1000858 CVE-2019-2708 CVE-2019-9169 CVE-2019-13050 CVE-2019-13627 CVE-2019-14889 CVE-2019-15903 CVE-2019-19906 CVE-2019-20454 CVE-2019-20934 CVE-2019-25013 CVE-2020-1730 CVE-2020-8231 CVE-2020-8284 CVE-2020-8285 CVE-2020-8286 CVE-2020-8927 CVE-2020-11668 CVE-2020-13434 CVE-2020-15358 CVE-2020-27618 CVE-2020-28196 CVE-2020-28469 CVE-2020-28500 CVE-2020-28851 CVE-2020-28852 CVE-2020-29361 CVE-2020-29362 CVE-2020-29363 CVE-2021-3326 CVE-2021-3377 CVE-2021-3449 CVE-2021-3450 CVE-2021-3516 CVE-2021-3517 CVE-2021-3518 CVE-2021-3520 CVE-2021-3537 CVE-2021-3541 CVE-2021-3560 CVE-2021-20271 CVE-2021-20305 CVE-2021-21272 CVE-2021-21309 CVE-2021-21321 CVE-2021-21322 CVE-2021-23337 CVE-2021-23343 CVE-2021-23346 CVE-2021-23362 CVE-2021-23364 CVE-2021-23368 CVE-2021-23369 CVE-2021-23382 CVE-2021-23383 CVE-2021-23839 CVE-2021-23840 CVE-2021-23841 CVE-2021-25217 CVE-2021-27219 CVE-2021-27292 CVE-2021-27358 CVE-2021-28092 CVE-2021-28918 CVE-2021-29418 CVE-2021-29477 CVE-2021-29478 CVE-2021-29482 CVE-2021-32399 CVE-2021-33033 CVE-2021-33034 CVE-2021-33502 CVE-2021-33623 CVE-2021-33909 CVE-2021-33910 ===================================================================== 1.

OpenSSL Security Advisory [25 March 2021] ========================================= CA certificate check bypass with X509_V_FLAG_X509_STRICT (CVE-2021-3450) ======================================================================== Severity: High The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a "purpose" has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named "purpose" values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verification routines, but it can be overridden or removed by an application. In order to be affected, an application must explicitly set the X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose. This issue was reported to OpenSSL on 18th March 2021 by Benjamin Kaduk from Akamai and was discovered by Xiang Ding and others at Akamai. The fix was developed by Tomáš Mráz. This issue was reported to OpenSSL on 17th March 2021 by Nokia. The fix was developed by Peter Kästle and Samuel Sapalski from Nokia.
