TITLE

Mozilla Network Security Services (NSS) fails to properly verify RSA signatures

DESCRIPTION

Mozilla Network Security Services (NSS) before 3.16.2.1, 3.16.x before 3.16.5, and 3.17.x before 3.17.1, as used in Mozilla Firefox before 32.0.3, Mozilla Firefox ESR 24.x before 24.8.1 and 31.x before 31.1.1, Mozilla Thunderbird before 24.8.1 and 31.x before 31.1.2, Mozilla SeaMonkey before 2.29.1, Google Chrome before 37.0.2062.124 on Windows and OS X, and Google Chrome OS before 37.0.2062.120, does not properly parse ASN.1 values in X.509 certificates, which makes it easier for remote attackers to spoof RSA signatures via a crafted certificate, aka a "signature malleability" issue. This vulnerability may allow an attacker to forge a RSA signature, such as a SSL certificate. Mozilla Network Security Services (NSS) The library contains DigestInfo There is a problem with the processing of RSA A vulnerability exists that does not properly verify signatures. Mozilla Network Security Services (NSS) Implemented by the library DigestInfo There is a vulnerability in the processing of. BER Encoded DigestInfo When parsing a field, the parsing of padded bytes is bypassed, PKCS#1 v1.5 Formal RSA Signature forgery may not be detected (CWE-295) . CWE-295: Improper Certificate Validation http://cwe.mitre.org/data/definitions/295.html This vulnerability 2006 Announced in the year Bleichenbacher vulnerability It is a kind of. Bleichenbacher vulnerability http://www.imc.org/ietf-openpgp/mail-archive/msg06063.html Mozilla NSS Is plural Linux Distributions and packages, and Google Chrome And Google Chrome OS It is used in etc. Other vulnerable libraries and products may have similar vulnerable implementations.SSL Certificate etc. RSA The signature may be forged. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions; this may aid in launching further attacks. For the testing distribution (jessie) and unstable distribution (sid), Icedove uses the system NSS library, handled in DSA 3033-1. He discovered that NSS is vulnerable to a variant of a signature forgery attack previously published by Daniel Bleichenbacher. This is due to lenient parsing of ASN.1 values involved in a signature and could lead to the forging of RSA certificates (CVE-2014-1568). The updated NSPR packages have been upgraded to the latest 4.10.7 version. The updated NSS packages have been upgraded to the latest 3.17.1 version which is not vulnerable to this issue. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-1568 https://www.mozilla.org/security/announce/2014/mfsa2014-73.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: d532128922a8701f24f1d1a22b8e544c mbs1/x86_64/lib64nspr4-4.10.7-1.mbs1.x86_64.rpm 86c469bff7f47669ecfbe711fced774c mbs1/x86_64/lib64nspr-devel-4.10.7-1.mbs1.x86_64.rpm a5384df3378e1d282d24520fe9234804 mbs1/x86_64/lib64nss3-3.17.1-1.mbs1.x86_64.rpm 63722882484c4e4a4b438ddb33911fe8 mbs1/x86_64/lib64nss-devel-3.17.1-1.mbs1.x86_64.rpm 5a9c51abf5c3650926e4cdb8997ec2b1 mbs1/x86_64/lib64nss-static-devel-3.17.1-1.mbs1.x86_64.rpm 8b639de0098277bc211ed8b9f83c9516 mbs1/x86_64/nss-3.17.1-1.mbs1.x86_64.rpm edd4b951a0f68c4264137489f0dada31 mbs1/x86_64/nss-doc-3.17.1-1.mbs1.noarch.rpm 32f6ffafd4984d00b01b43e9b38fe344 mbs1/x86_64/rootcerts-20140805.00-1.mbs1.x86_64.rpm fa908930395265a0dbad1029252679ef mbs1/x86_64/rootcerts-java-20140805.00-1.mbs1.x86_64.rpm fb338172cf421a95728ec28412d2fed1 mbs1/SRPMS/nspr-4.10.7-1.mbs1.src.rpm 3c721493672c05aa7960aca11e3b1533 mbs1/SRPMS/nss-3.17.1-1.mbs1.src.rpm 8b79fa2baeaac0b531d7cb01c5a419b4 mbs1/SRPMS/rootcerts-20140805.00-1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.

Summary: An updated rhev-hypervisor6 package that fixes several security issues is now available. Red Hat Product Security has rated this update as having Critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEV-M 3.4 - noarch 3. Description: The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: a subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found in the way Bash evaluated certain specially crafted environment variables. An attacker could use this flaw to override or bypass environment restrictions to execute shell commands. (CVE-2014-6271) It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. An attacker could potentially use this flaw to override or bypass environment restrictions to execute shell commands. (CVE-2014-7169) A flaw was found in the way NSS parsed ASN.1 (Abstract Syntax Notation One) input from certain RSA signatures. (CVE-2014-1568) It was discovered that the fixed-sized redir_stack could be forced to overflow in the Bash parser, resulting in memory corruption, and possibly leading to arbitrary code execution when evaluating untrusted input that would not otherwise be run as code. (CVE-2014-7186) An off-by-one error was discovered in the way Bash was handling deeply nested flow control constructs. Depending on the layout of the .bss segment, this could allow arbitrary execution of code that would not otherwise be executed by Bash. (CVE-2014-7187) Red Hat would like to thank Stephane Chazelas for reporting CVE-2014-6271, and the Mozilla project for reporting CVE-2014-1568. Upstream acknowledges Antoine Delignat-Lavaud and Intel Product Security Incident Response Team as the original reporters of CVE-2014-1568. The CVE-2014-7186 and CVE-2014-7187 issues were discovered by Florian Weimer of Red Hat Product Security. Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package. 4. Solution: This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 To upgrade Hypervisors in Red Hat Enterprise Virtualization environments using the disk image provided by this package, refer to: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/ht ml/Hypervisor_Deployment_Guide/chap-Deployment_Guide-Upgrading_Red_Hat_Ente rprise_Virtualization_Hypervisors.html 5.
