EulerOS 2.0 SP2 : openssl098e (EulerOS-SA-2017-1039)

High Nessus Plugin ID 99884


The remote EulerOS host is missing multiple security updates.


According to the versions of the openssl098e package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0 does not properly validate division results, which allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly have unspecified other impact via unknown vectors.(CVE-2016-2182)

- A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections form other clients.(CVE-2016-8610)

- A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks.(CVE-2015-3197)

- A padding oracle flaw was found in the Secure Sockets Layer version 2.0 (SSLv2) protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack is publicly referred to as DROWN.(CVE-2016-0800)

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.


Update the affected openssl098e packages.
