An update for openssl is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es) :

* openssl: 0-byte record padding oracle (CVE-2019-1559)

* openssl: timing side channel attack in the DSA signature algorithm (CVE-2018-0734)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Additional Changes :

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.7 Release Notes linked from the References section.

According to the version of the openssl packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - The OpenSSL DSA signature algorithm has been shown to     be vulnerable to a timing side channel attack. An     attacker could use variations in the signing algorithm     to recover the private key. (CVE-2018-0734)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An     attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a     (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected     1.0.2-1.0.2p). (CVE-2018-0734)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update for virtualbox to version 6.0.10 fixes the following issues :

Security issues fixed :

  - CVE-2019-2859 CVE-2019-2867 CVE-2019-2866 CVE-2019-2864     CVE-2019-2865 CVE-2019-1543 CVE-2019-2863 CVE-2019-2848     CVE-2019-2877 CVE-2019-2873 CVE-2019-2874 CVE-2019-2875     CVE-2019-2876 CVE-2019-2850 (boo#1141801)

The version of Node.js installed on the remote host is 6.x prior to 6.15.0, 8.x prior to 8.14.0 or 10.x prior to 10.14.0 or 11.x prior to 11.3.0. It is, therefore, affected by multiple vulnerabilities.

  - OpenSSL Timing vulnerability in DSA signature generation (CVE-2018-0734).

  - OpenSSL Timing vulnerability in ECDSA signature generation (CVE-2018-0735).

  - OpenSSL Microarchitecture timing vulnerability in ECC scalar multiplication (CVE-2018-5407).

  - Debugger port 5858 listens on any interface by default  CVE-2018-12120).

  - Denial of Service with large HTTP headers (CVE-2018-12121).

  - Slowloris HTTP Denial of Service (CVE-2018-12122).

  - Hostname spoofing in URL parser for javascript protocol (CVE-2018-12123).

  - HTTP request splitting (CVE-2018-12116).

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of AOS installed on the remote host is prior to 5.10.9. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.10.9 advisory.

  - Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow     can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels,     assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass     invalid utf-8 strings to functions like pango_itemize. (CVE-2019-1010238)

  - curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal     function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how     large temporary storage area to allocate from the heap. The length value is then subsequently used to     iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit     size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31     bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the     intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is     almost identical to CVE-2017-8816.) (CVE-2018-14618)

  - An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can     send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed     later on, leading to DoS (segmentation fault). (CVE-2018-14598)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable     to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other     impact. (CVE-2018-14599)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a     variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading     to DoS or remote code execution. (CVE-2018-14600)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several local side channel attacks and a denial of service via large Diffie-Hellman parameters were discovered in OpenSSL, a Secure Sockets Layer toolkit.

Patch for CVE-2018-0737, CVE-2018-0732, CVE-2018-0734, CVE-2019-1552, CVE-2019-1559.

CVE-2016-8610: Adjusted current fix and add missing error string (bsc#1110018).

Add missing timing side channel patch for DSA signature generation (bsc#1113742).

Fixed the 'One and Done' side-channel attack on RSA (bsc#1104789).
