Red Hat: RHSA-2017-0240-01 High: openssl Security Vulnerability

Updated glibc packages that fix two security issues and two bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Critical: glibc security and bug fix update Advisory ID: RHSA-2016:0176-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:0176.html Issue date: 2016-02-16 CVE Names: CVE-2015-5229 CVE-2015-7547 ==================================================================== 1. Summary: Updated glibc packages that fix two security issues and two bugs are now available for Red Hat Enterprise Linux 7. 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: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. A stack-based buffer overflow was foundin the way the libresolv library performed dual A/AAAA DNS queries. A remote attacker could create a specially crafted DNS response which could cause libresolv to crash or, potentially, execute code with the permissions of the user running the library. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module. (CVE-2015-7547) It was discovered that the calloc implementation in glibc could return memory areas which contain non-zero bytes. This could result in unexpected application behavior such as hangs or crashes. (CVE-2015-5229) The CVE-2015-7547 issue was discovered by the Google Security Team and Red Hat. Red Hat would like to thank Jeff Layton for reporting the CVE-2015-5229 issue. This update also fixes the following bugs: * The existing implementation of the "free" function causes all memory pools beyond the first to return freed memory directly to the operating system as quickly as possible. This can result in performance degradation when the rate of free calls is very high. The first memory pool (the main pool) does provide a method to rate limit the returns via M_TRIM_THRESHOLD, but this method is not available to subsequent memory pools. With this update, the M_TRIM_THRESHOLD method is extended to apply to all memory pools, which improves performance for threads with very high amounts of free calls and limits the number of "madvise" system calls. The change also increases the total transient memory usage by processes because the trim threshold must be reached before memory can be freed. To return to the previous behavior, you can either set M_TRIM_THRESHOLD using the "mallopt" function, or set the MALLOC_TRIM_THRESHOLD environment variable to 0. (BZ#1298930) * On the little-endian variant of 64-bit IBM Power Systems (ppc64le), a bug in the dynamic loader could cause applications compiled with profiling enabled to fail to start with the error "monstartup: out of memory". The bug has been corrected and applications compiled for profiling now start correctly.(BZ#1298956) All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1256285 - CVE-2015-5229 glibc: calloc may return non-zero memory 1293532 - CVE-2015-7547 glibc: getaddrinfo stack-based buffer overflow 1298956 - "monstartup: out of memory" on PPC64LE [rhel-7.2.z] 6.

Red Hat: RHSA-2010:0977 Moderate: OpenSSL Ciphersuite Downgrade Issue

Updated openssl packages that fix three security issues are now available for Red Hat Enterprise Linux 4. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: openssl security update Advisory ID: RHSA-2010:0977-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2010:0977.html Issue date: 2010-12-13 CVE Names: CVE-2008-7270 CVE-2009-3245 CVE-2010-4180 ==================================================================== 1. Summary: Updated openssl packages that fix three security issues are now available for Red Hat Enterprise Linux 4. The Red Hat Security Response Team has rated this update as having moderate 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: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server code. A remote attacker could possibly use this flaw to change the ciphersuite associated with a cached session stored on the server, if the server enabled the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option, possibly forcing the client to use a weaker ciphersuite after resuming thesession. (CVE-2010-4180, CVE-2008-7270) Note: With this update, setting the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option has no effect and this bug workaround can no longer be enabled. It was discovered that OpenSSL did not always check the return value of the bn_wexpand() function. An attacker able to trigger a memory allocation failure in that function could possibly crash an application using the OpenSSL library and its UBSEC hardware engine support. (CVE-2009-3245) All OpenSSL users should upgrade to these updated packages, which contain backported patches to resolve these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. 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 5. Bugs fixed (http://bugzilla.redhat.com/): 570924 - CVE-2009-3245 openssl: missing bn_wexpand return value checks 659462 - CVE-2010-4180 openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG ciphersuite downgrade attack 660650 - CVE-2008-7270 openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG downgrade-to-disabled ciphersuite attack 6.
