CVE-2018-10844 [MEDIUM] GnuTLS vulnerabilities
Title: GnuTLS vulnerabilities
Summary: Several security issues were fixed in GnuTLS.
Eyal Ronen, Kenneth G. Paterson, and Adi Shamir discovered that GnuTLS was
vulnerable to a timing side-channel attack known as the "Lucky Thirteen"
issue. A remote attacker could possibly use this issue to perform
plaintext-recovery attacks via analysis of timing data. This issue only
affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-10844,
CVE-2018-10845, CVE-2018-10846)
Tavis Ormandy discovered that GnuTLS incorrectly handled memory when
verifying certain X.509 certificates. A remote attacker could use this
issue to cause GnuTLS to crash, resulting in a denial of service, or
possibly execute arbitrary code. This issue only affected Ubuntu 18.04 LTS,
Ubuntu 18.10, and Ubuntu 19.04. (CVE-2019-38
