Debian 8 Jessie: DLA-1840-1 Critical: golang-go.crypto Salsa20 Flaw

A flaw was found in the amd64 implementation of salsa20. If more than 256 GiB of keystream is generated, or if the counter otherwise grows greater than 32 bits, the amd64 implementation will first generate incorrect output, and then cycle back to previously generated keystream. . Package : golang-go.crypto Version : 0.0~hg190-1+deb8u1 CVE ID : CVE-2019-11840 A flaw was found in the amd64 implementation of salsa20. If more than 256 GiB of keystream is generated, or if the counter otherwise grows greater than 32 bits, the amd64 implementation will first generate incorrect output, and then cycle back to previously generated keystream. For Debian 8 "Jessie", this problem has been fixed in version 0.0~hg190-1+deb8u1. obfs4proxy has been rebuilt as version 0.0.3-2+deb8u1. We recommend that you upgrade your golang-golang-x-crypto-dev and obfs4proxy packages, and rebuild any software using golang-golang-x-crypto-dev. Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS . Revise golang-go.crypto on Debian LTS to address keystream vulnerability impacting amd64 version. Essential security patch required..

Gentoo: 202310-15 Alert: OpenSSL RSA Signing Vulnerability Notice

OpenSSL fails to properly validate PKCS #1 v1.5 signatures.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200609-05 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: OpenSSL, AMD64 x86 emulation base libraries: RSA signature forgery Date: September 07, 2006 Bugs: #146375, #146438 ID: 200609-05 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= OpenSSL fails to properly validate PKCS #1 v1.5 signatures. Background ========= OpenSSL is a toolkit implementing the Secure Sockets Layer, Transport Layer Security protocols and a general-purpose cryptography library. The x86 emulation base libraries for AMD64 contain a vulnerable version of OpenSSL. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 openssl < 0.9.7k > = 0.9.7k 2 emul-x86-linux-baselibs < 2.5.2 > = 2.5.2 ------------------------------------------------------------------- # Package 2 [app-emulation/emul-x86-linux-baselibs] only applies to AMD64 users. NOTE: Any packages listed without architecture tags apply to all architectures... ------------------------------------------------------------------- 2 affected packages ------------------------------------------------------------------- Description ========== Daniel Bleichenbacher discovered that it might be possible to forge signatures signed by RSA keys with the exponent of 3. Impact ===== Since several CAs are using an exponent of 3it might be possible for an attacker to create a key with a false CA signature. Workaround ========= There is no known workaround at this time. Resolution ========= All OpenSSL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-libs/openssl-0.9.7k" All AMD64 x86 emulation base libraries users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =app-emulation/emul-x86-linux-baselibs-2.5.2" References ========= [ 1 ] CVE-2006-4339 https://www.cve.org/CVERecord?id=CVE-2006-4339 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200609-05 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
