Scientific Linux Security Update : ntp on SL6.x, SL7.x i386/x86_64 (20141220)

Multiple buffer overflow flaws were discovered in ntpd's cryptorecv, ctlputdata, and configure functions. A remote attacker could use either of these flaws to send a specially crafted request packet that could crash ntpd or, potentially, execute arbitrary code with the privileges of the ntp user...

Authentication flaw

The receive function in ntpproto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets...

CVE-2014-9296

CVE-2014-9296 affects ntpd in NTP up to version 4.2.8, arising from a missing return on error in receive() (ntp_proto.c). This could allow remote attackers to trigger an unintended association change by sending crafted packets. The connected advisories indicate affected deployments include multip...

CVE-2014-9293

The configauth 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...

CVE-2014-9293: Undefined Security Weakness

The configauth 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...

CVE-2014-9295: Improper Restriction of Operations within the Bounds of a Memory Buffer

Multiple stack-based buffer overflows in ntpd in NTP before 4.2.8 allow remote attackers to execute arbitrary code via a crafted packet, related to 1 the cryptorecv function when the Autokey Authentication feature is used, 2 the ctlputdata function, and 3 the configure function...

Important: ntp

Issue Overview: It was found that ntpd automatically generated weak keys for its internal use if no ntpdc request authentication key was specified in the ntp.conf configuration file. A remote attacker able to match the configured IP restrictions could guess the generated key, and possibly use it ...

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

Overview 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...

CVE-2013-5211

The monlist feature in ntprequest.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service traffic amplification via forged 1 REQMONGETLIST or 2 REQMONGETLIST1 requests, as exploited in the wild in December 2013...

Security feature bypass

The monlist feature in ntprequest.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service traffic amplification via forged 1 REQMONGETLIST or 2 REQMONGETLIST1 requests, as exploited in the wild in December 2013...

CVE-2013-5211

The ntpd implementation of the Network Time Protocol (NTP) before version 4.2.7p26 is vulnerable to a denial of service (DoS) via traffic amplification. A remote attacker can exploit the monlist feature in ntp_request.c by sending forged REQ_MON_GETLIST or REQ_MON_GETLIST_1 requests. Due to insuf...

Network Time Protocol Daemon (ntpd) monlist Command Enabled DoS

The version of ntpd running on the remote host has the 'monlist' command enabled. This command returns a list of recent hosts that have connected to the service. However, it is affected by a denial of service vulnerability in ntprequest.c that allows an unauthenticated, remote attacker to saturat...

CVE-2013-5211: Improper Input Validation

The monlist feature in ntprequest.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service traffic amplification via forged 1 REQMONGETLIST or 2 REQMONGETLIST1 requests, as exploited in the wild in December 2013...
