The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3872-1 advisory. It was discovered that a race condition existed in the vsock address family implementation of the Linux kernel that could lead to a use-after-free...

Researchers Allege 'Systemic' Privacy, Security Flaws in Popular IoT Devices

Researchers are highlighting the insecure nature of Internet of Things devices in a report released Tuesday alleging a bevy of popular consumer connected devices sold at major retailers such as Walmart and Best Buy are riddled with security holes and privacy issues. In analyzing 12 different IoT...

USN-3871-1: Linux kernel vulnerabilities

Wen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service system crash or possibly execute arbitrary code...

What is a vulnerability and what is not?

It looks like a pretty simple question. I used it to started my MIPT lecture. But actually the answer is not so obvious. There are lots of formal definitions of a vulnerability. For example in NIST Glossary there are 17 different definitions. The most popular one used in 13 documents is:...

Security advisory YSA-2019-01 | Yubico

Yubico library libu2f-host prior to version 1.1.7 contains an unchecked buffer, which could allow a buffer overflow. Libu2f-host is a library that implements the host party of the U2F protocol. This issue can allow an attacker with a custom made malicious USB device masquerading as a security key...

CVE-2018-5737

CVE-2018-5737 concerns ISC BIND 9.12.x. The issue arises from the implementation of the new serve-stale feature, which can trigger an assertion failure in rbtdb.c even when stale-answer-enable is off. Additionally, interaction between serve-stale and NSEC aggressive negative caching can, in some ...

CVE-2019-3557

The implementations of streams for bz2 and php://output improperly implemented their readImpl functions, returning -1 consistently. This behavior caused some stream functions, such as streamgetline, to trigger an out-of-bounds read when operating on such malformed streams. The implementations wer...

36-Year-Old SCP Clients' Implementation Flaws Discovered

A set of 36-year-old vulnerabilities has been uncovered in the Secure Copy Protocol SCP implementation of many client applications that can be exploited by malicious servers to overwrite arbitrary files in the SCP client target directory unauthorizedly. Session Control Protocol SCP, also known as...

Improper Encryption Implementation

erlang has an improper encryption implementation. The Erlang otp TLS server answers with different TLS alerts to different error types in the RSA PKCS 1 1.5 padding. This allows an attacker to decrypt content or sign messages with the server's private key this is a variation of the Bleichenbacher...

Timing Attack

tomcat-catalina is vulnerable to timing attacks. When the supplied username does not exist, the Realm implementation will not process the supplied password, making a timing attack possible to determine valid usernames. Note that the default configuration includes the LockOutRealm which makes...

Authorization Bypass

kernel-rt is vulnerable to authorization bypass attacks. The vulnerability exists as the Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access...

Information Disclosure

icedtea-web is vulnerable to information disclosure attacks. The vulnerability exists as the LiveConnect implementation in plugin/icedteanp/IcedTeaNPPlugin.cc in IcedTea-Web before 1.4.2 allows local users to read the messages between a Java applet and a web browser by pre-creating a temporary...

Authorization Bypass

qemu-kvm is vulnerable to authorization bypass attacks. The vulnerability exists through a buffer overflow in the SCSI implementation in QEMU, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as the epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service through a crafted application...
