TITLE

OpenSSL Information disclosure vulnerability

DESCRIPTION

If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q). An attacker can exploit this issue to gain access to sensitive information that may aid in further attacks. The product supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, secure hash algorithms, etc. A vulnerability in OpenSSL could allow an unauthenticated, remote malicious user to access sensitive information on a targeted system. An attacker who is able to perform man-in-the-middle attacks could exploit the vulnerability by persuading a user to access a link that submits malicious input to the affected software. A successful exploit could allow the malicious user to intercept and modify the browser requests and then observe the server behavior in order to conduct a padding oracle attack and decrypt sensitive information. The appliance is available to download as an OVA file from the Customer Portal. For the stable distribution (stretch), this problem has been fixed in version 1.0.2r-1~deb9u1.

Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/openssl < 1.0.2r >= 1.0.2r Description =========== Multiple vulnerabilities have been discovered in OpenSSL. Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker to obtain sensitive information, caused by the failure to immediately close the TCP connection after the hosts encounter a zero-length record with valid padding. A local attacker could run a malicious process next to legitimate processes using the architectureas parallel thread running capabilities to leak encrypted data from the CPU's internal processes. 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-1.0.2r" References ========== [ 1 ] CVE-2018-5407 https://nvd.nist.gov/vuln/detail/CVE-2018-5407 [ 2 ] CVE-2019-1559 https://nvd.nist.gov/vuln/detail/CVE-2019-1559 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201903-10 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.
