CVE-2021-23839


TITLE

OpenSSL  Cryptographic strength vulnerabilities in

Trust: 0.8

sources: JVNDB: JVNDB-2021-003872

DESCRIPTION

OpenSSL 1.0.2 supports SSLv2. If a client attempts to negotiate SSLv2 with a server that is configured to support both SSLv2 and more recent SSL and TLS versions then a check is made for a version rollback attack when unpadding an RSA signature. Clients that support SSL or TLS versions greater than SSLv2 are supposed to use a special form of padding. A server that supports greater than SSLv2 is supposed to reject connection attempts from a client where this special form of padding is present, because this indicates that a version rollback has occurred (i.e. both client and server support greater than SSLv2, and yet this is the version that is being requested). The implementation of this padding check inverted the logic so that the connection attempt is accepted if the padding is present, and rejected if it is absent. This means that such as server will accept a connection if a version rollback attack has occurred. Further the server will erroneously reject a connection if a normal SSLv2 connection attempt is made. Only OpenSSL 1.0.2 servers from version 1.0.2s to 1.0.2x are affected by this issue. In order to be vulnerable a 1.0.2 server must: 1) have configured SSLv2 support at compile time (this is off by default), 2) have configured SSLv2 support at runtime (this is off by default), 3) have configured SSLv2 ciphersuites (these are not in the default ciphersuite list) OpenSSL 1.1.1 does not have SSLv2 support and therefore is not vulnerable to this issue. The underlying error is in the implementation of the RSA_padding_check_SSLv23() function. This also affects the RSA_SSLV23_PADDING padding mode used by various other functions. Although 1.1.1 does not support SSLv2 the RSA_padding_check_SSLv23() function still exists, as does the RSA_SSLV23_PADDING padding mode. Applications that directly call that function or use that padding mode will encounter this issue. However since there is no support for the SSLv2 protocol in 1.1.1 this is considered a bug and not a security issue in that version. OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.0.2y (Affected 1.0.2s-1.0.2x). OpenSSL There is a security level vulnerability in.Information may be tampered with. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. -----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 [16 February 2021] ============================================ Null pointer deref in X509_issuer_and_serial_hash() (CVE-2021-23841) ==================================================================== Severity: Moderate The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. This issue was reported to OpenSSL on 15th December 2020 by Tavis Ormandy from Google. The fix was developed by Matt Caswell. Incorrect SSLv2 rollback protection (CVE-2021-23839) ==================================================== Severity: Low OpenSSL 1.0.2 supports SSLv2. This issue was reported to OpenSSL on 21st January 2021 by D. Katz and Joel Luellwitz from Trustwave. The fix was developed by Matt Caswell. Integer overflow in CipherUpdate (CVE-2021-23840) ================================================= Severity: Low Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. This issue was reported to OpenSSL on 13th December 2020 by Paul Kehrer. The fix was developed by Matt Caswell.
