CVE-2014-9293

TITLE

NTP Project Network Time Protocol daemon (ntpd) contains multiple vulnerabilities (Updated)

DESCRIPTION

The config_auth function in ntpd in NTP before 4.2.7p11, when an auth key is not configured, improperly generates a key, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. The NTP Project ntpd version 4.2.7 and pervious versions contain several vulnerabilities. ntp-keygen prior to version 4.2.7p230 also uses a non-cryptographic random number generator when generating symmetric keys. These vulnerabilities may affect ntpd acting as a server or client. Supplementary information : CWE Vulnerability types by CWE-332: Insufficient Entropy in PRNG (PRNG Insufficient entropy in ) Has been identified. http://cwe.mitre.org/data/definitions/332.htmlBrute force attack by a third party (Brute force attack) Could be used to break cryptographic protection mechanisms. NTP is prone to a security weakness. An attacker can exploit this issue to guess the generated key, and possibly use it to send an ntpdc query or configuration requests. Network Time Protocol is prone to multiple stack-based buffer-overflow vulnerabilities because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Successful exploits may allow an attacker to execute arbitrary code with the privileges of the ntpd process. Failed attempts will likely cause a denial-of-service condition. Network Time Protocol is prone to an unspecified security vulnerability. Little is known about this issue or its effects at this time. We will update this BID as more information emerges. Network Time Protocol 4.2.7 is vulnerable; other versions may also be affected. 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(). 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). _______________________________________________________________________ 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.

On December 19, 2014, NTP.org and US-CERT released security advisories detailing two issues regarding weak cryptographic pseudorandom number generation (PRNG), three buffer overflow vulnerabilities, and an unhandled error condition with an unknown impact. Cisco will release free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: ntp security update Advisory ID: RHSA-2014:2025-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-2025.html Issue date: 2014-12-20 CVE Names: CVE-2014-9293 CVE-2014-9294 CVE-2014-9295 ===================================================================== 1. Summary: Updated ntp packages that fix several security issues are now available for Red Hat Enterprise Linux 5. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Multiple buffer overflow flaws were discovered in ntpd's crypto_recv(), ctl_putdata(), and configure() functions. Note: the crypto_recv() flaw requires non-default configurations to be active, while the ctl_putdata() flaw, by default, can only be exploited via local attackers, and the configure() flaw requires additional authentication to exploit. (CVE-2014-9293) It was found that ntp-keygen used a weak method for generating MD5 keys. Note: it is recommended to regenerate any MD5 keys that had explicitly been generated with ntp-keygen; the default installation does not contain such keys). (CVE-2014-9294) All ntp users are advised to upgrade to this updated package, which contains backported patches to resolve these issues. After installing the update, the ntpd daemon will restart automatically. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5.
