New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the libpcap package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- Libpcap provides a portable framework for low-level network monitoring. Libpcap can provide network statistics collection,security monitoring and network debugging. Since almost every system vendor provides a different interface for packet capture, the libpcap authors created this system-independent API to ease in porting and to alleviate the need for several system-dependent packet capture modules in each application.Install libpcap if you need to do low-level network traffic monitoring on your network.Security Fix(es):rpcapd/daemon.c in libpcap before 1.9.1 mishandles certain length values because of reuse of a variable. This may open up an attack vector involving extra data at the end of a request.(CVE-2019-15161)rpcapd/daemon.c in libpcap before 1.9.1 on non-Windows platforms provides details about why authentication failed, which might make it easier for attackers to enumerate valid usernames.(CVE-2019-15162)rpcapd/daemon.c in libpcap before 1.9.1 allows attackers to cause a denial of service (NULL pointer dereference and daemon crash) if a crypt() call fails.(CVE-2019-15163)rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source.(CVE-2019-15164)sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory.(CVE-2019-15165)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
