Kategorie:	Mageia Linux Local Security Checks
Titel:	Mageia: Security Advisory (MGASA-2017-0371)
Zusammenfassung:	The remote host is missing an update for the 'ruby, ruby-json' package(s) announced via the MGASA-2017-0371 advisory.
Beschreibung:	Summary: The remote host is missing an update for the 'ruby, ruby-json' package(s) announced via the MGASA-2017-0371 advisory. Vulnerability Insight: If a malicious format string which contains a precious specifier (*) is passed and a huge minus value is also passed to the specifier, buffer underrun may be caused. In such situation, the result may contains heap, or the Ruby interpreter may crash (CVE-2017-0898). If a malicious string is passed to the decode method of OpenSSL::ASN1, buffer underrun may be caused and the Ruby interpreter may crash (CVE-2017-14033). The generate method of JSON module optionally accepts an instance of JSON::Ext::Generator::State class. If a malicious instance is passed, the result may include contents of heap (CVE-2017-14064). When using the Basic authentication of WEBrick, clients can pass an arbitrary string as the user name. WEBrick outputs the passed user name intact to its log, then an attacker can inject malicious escape sequences to the log and dangerous control characters may be executed on a victim's terminal emulator (CVE-2017-10784). Affected Software/OS: 'ruby, ruby-json' package(s) on Mageia 5, Mageia 6. Solution: Please install the updated package(s). CVSS Score: 9.3 CVSS Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
