-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:003 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : ntp Date : January 5, 2015 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Updated ntp packages fix security vulnerabilities: If no authentication key is defined in the ntp.conf file, a cryptographically-weak default key is generated (CVE-2014-9293). ntp-keygen before 4.2.7p230 uses a non-cryptographic random number generator with a weak seed to generate symmetric keys (CVE-2014-9294). A remote unauthenticated attacker may craft special packets that trigger buffer overflows in the ntpd functions crypto_recv() (when using autokey authentication), ctl_putdata(), and configure(). The resulting buffer overflows may be exploited to allow arbitrary malicious code to be executed with the privilege of the ntpd process (CVE-2014-9295). A section of code in ntpd handling a rare error is missing a return statement, therefore processing did not stop when the error was encountered. This situation may be exploitable by an attacker (CVE-2014-9296). The ntp package has been patched to fix these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9293 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9294 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9295 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9296 http://advisories.mageia.org/MGASA-2014-0541.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 25fe56fc0649ac9bb83be467969c2380 mbs1/x86_64/ntp-4.2.6p5-8.1.mbs1.x86_64.rpm 9409f5337bc2a2682e09db81e769cd5c mbs1/x86_64/ntp-client-4.2.6p5-8.1.mbs1.x86_64.rpm df65cc9c536cdd461e1ef95318ab0d3b mbs1/x86_64/ntp-doc-4.2.6p5-8.1.mbs1.x86_64.rpm 53f446bffdf6e87726a9772e946c5e34 mbs1/SRPMS/ntp-4.2.6p5-8.1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
