Design/Logic Flaw

Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSHPROMISE. The peer spends ti...

Design/Logic Flaw

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...

CVE-2019-9518

Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSHPROMISE. The peer spends ti...

CVE-2019-9515 Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service

Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost...

CVE-2019-9517 Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service

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...

NewStart CGSL CORE 5.04 / MAIN 5.04 : 389-ds-base Vulnerability (NS-SA-2019-0062)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has 389-ds-base packages installed that are affected by a vulnerability: - It was found that a specially crafted search query could lead to excessive CPU consumption in the dosearch function. An unauthenticated attacker could u...

NewStart CGSL MAIN 4.05 : gnutls Multiple Vulnerabilities (NS-SA-2019-0109)

The remote NewStart CGSL host, running version MAIN 4.05, has gnutls packages installed that are affected by multiple vulnerabilities: - Stack-based buffer overflow in the cdkpkgetkeyid function in lib/opencdk/pubkey.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have...

CVE-2019-10171

It was found that the fix for CVE-2018-14648 in 389-ds-base, versions 1.4.0.x before 1.4.0.17, was incorrectly applied in RHEL 7.5. An attacker would still be able to provoke excessive CPU consumption leading to a denial of service...

CVE-2019-14442

In mpc8readheader in libavformat/mpc8.c in Libav 12.3, an input file can result in an avioseek infinite loop and hang, with 100% CPU consumption. Attackers could leverage this vulnerability to cause a denial of service via a crafted file...

Denial Of Service (DoS)

389-ds-base is vulnerable to denial of service. It was found that a malicious search query could lead to excessive CPU consumption in the dosearch function. An unauthenticated attacker could use this flaw to provoke a denial of service. This vulnerability exists due to an insufficient fix for...

EulerOS 2.0 SP2 : expat (EulerOS-SA-2019-1742)

According to the versions of the expat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Multiple integer overflows in the XMLGetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products,...

EulerOS Virtualization for ARM 64 3.0.2.0 : expat (EulerOS-SA-2019-1698)

According to the versions of the expat packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - The XML parser in Expat does not use sufficient entropy for hash initialization, which allows context-dependent attacke...

Denial Of Service (DoS)

expat is vulnerable to denial of service DoS. The attack exists because XML parser does not validate and handle the XML names input with large number of colons, consuming high CPU and memory...
