| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2019-9514 | Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. | [email protected] | 7.5 | 82.81% | 2019-08-13 | 2026-06-16 |
| 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. | [email protected] | 7.5 | 82.02% | 2019-08-13 | 2026-06-16 |
| 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, memory, or both. | [email protected] | 7.5 | 83.43% | 2019-08-13 | 2026-06-16 |
| CVE-2019-9511 | Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | [email protected] | 7.5 | 58.37% | 2019-08-13 | 2026-06-16 |

This can cause performance problems with large objects in cache. This affects versions 6.0.0 to 6.2.2 and 7.0.0 to 7.1.3. To resolve this issue users running 6.x users should upgrade to 6.2.3 or later versions and 7.x users should upgrade to 7.1.4 or later versions. | [email protected] | 5.3 | 6.89% | 2018-08-29 | 2026-06-16 |
| CVE-2018-8004 | There are multiple HTTP smuggling and cache poisoning issues when clients making malicious requests interact with Apache Traffic Server (ATS). This affects versions 6.0.0 to 6.2.2 and 7.0.0 to 7.1.3. To resolve this issue users running 6.x should upgrade to 6.2.3 or later versions and 7.x users should upgrade to 7.1.4 or later versions. | [email protected] | 6.5 | 6.31% | 2018-08-29 | 2026-06-16 |
