Nginx 1.17.x < 1.17.3 Multiple Vulnerabilties

According to its Server response header, the installed version of nginx is 1.9.5 to 1.16.0 or 1.17.x prior to 1.17.3. It is, therefore, affected by the following issues : - An excessive CPU usage in HTTP/2 with small window updates exists related to the module 'ngxhttpv2module'. CVE-2019-9511 - A...

Debian DLA-1884-1 : linux security update

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-18509 Denis Andzakovic reported a missing type check in the IPv4 multicast routing implementation. A user with the CAPNETADMIN capability in a...

DEBIAN-CVE-2019-9517

Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write many of the byt...

CVE-2019-9513

Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU...

UBUNTU-CVE-2019-9512

Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU,...

389-ds-base: Insufficient fix for CVE-2018-14648 denial of service in RHEL-7.5

It was found that the fix for CVE-2018-14648 was incorrectly applied in RHEL 7.5. An attacker would still be able to provoke excessive CPU consumption leading to a denial of service...

Regular Expression Denial Of Service (ReDoS)

marked is vulnerable to regular expression denial of service DoS. The attack is possible because it does not use efficient link tags in regular expression, thereby leading to a high CPU usage if an attacker parses an input link with nested parenthesis containing a large number of link tokens to t...
