var-202201-1080
Vulnerability from variot
There is a carry propagation bug in the MIPS32 and MIPS64 squaring procedure. Many EC algorithms are affected, including some of the TLS 1.3 default curves. Impact was not analyzed in detail, because the pre-requisites for attack are considered unlikely and include reusing private keys. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH private key among multiple clients, which is no longer an option since CVE-2016-0701. This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0.0. It was addressed in the releases of 1.1.1m and 3.0.1 on the 15th of December 2021. For the 1.0.2 release it is addressed in git commit 6fc1aaaf3 that is available to premium support customers only. It will be made available in 1.0.2zc when it is released. The issue only affects OpenSSL on MIPS platforms. Fixed in OpenSSL 3.0.1 (Affected 3.0.0). Fixed in OpenSSL 1.1.1m (Affected 1.1.1-1.1.1l). Fixed in OpenSSL 1.0.2zc-dev (Affected 1.0.2-1.0.2zb). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202210-02

Debian Security Advisory DSA-5103-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso March 15, 2022 https://www.debian.org/security/faq
Package : openssl CVE ID : CVE-2021-4160 CVE-2022-0778 Debian Bug : 989604
Tavis Ormandy discovered that the BN_mod_sqrt() function of OpenSSL could be tricked into an infinite loop. This could result in denial of service via malformed certificates.
For the oldstable distribution (buster), this problem has been fixed in version 1.1.1d-0+deb10u8.
For the stable distribution (bullseye), this problem has been fixed in version 1.1.1k-1+deb11u2.
For the detailed security status of openssl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/openssl

"data": "There is a carry propagation bug in the MIPS32 and MIPS64 squaring procedure. Many EC algorithms are affected, including some of the TLS 1.3 default curves. Impact was not analyzed in detail, because the pre-requisites for attack are considered unlikely and include reusing private keys. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH private key among multiple clients, which is no longer an option since CVE-2016-0701. This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0.0. It was addressed in the releases of 1.1.1m and 3.0.1 on the 15th of December 2021. For the 1.0.2 release it is addressed in git commit 6fc1aaaf3 that is available to premium support customers only. It will be made available in 1.0.2zc when it is released. The issue only affects OpenSSL on MIPS platforms. Fixed in OpenSSL 3.0.1 (Affected 3.0.0). Fixed in OpenSSL 1.1.1m (Affected 1.1.1-1.1.1l). Fixed in OpenSSL 1.0.2zc-dev (Affected 1.0.2-1.0.2zb). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nGentoo Linux Security Advisory GLSA 202210-02\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n https://security.gentoo.org/\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\n Severity: Normal\n Title: OpenSSL: Multiple Vulnerabilities\n Date: October 16, 2022\n Bugs: #741570, #809980, #832339, #835343, #842489, #856592\n ID: 202210-02\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nSynopsis\n========\n\nMultiple vulnerabilities have been discovered in OpenSSL, the worst of\nwhich could result in denial of service. \n\nBackground\n==========\n\nOpenSSL is an Open Source toolkit implementing the Secure Sockets Layer\n(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general\npurpose cryptography library. \n\nAffected packages\n=================\n\n -------------------------------------------------------------------\n Package / Vulnerable / Unaffected\n -------------------------------------------------------------------\n 1 dev-libs/openssl \u003c 1.1.1q \u003e= 1.1.1q\n\nDescription\n===========\n\nMultiple vulnerabilities have been discovered in OpenSSL.
