--- Begin Message ---Source: nginx Version: 1.14.2-2 Severity: grave Tags: security upstream Justification: user security hole Control: found -1 1.10.3-1+deb9u2 Control: found -1 1.10.3-1 Hi, The following vulnerabilities were published for nginx. CVE-2019-9511[0]: | 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. CVE-2019-9513[1]: | 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-2019-9516[2]: | Some HTTP/2 implementations are vulnerable to a header leak, | potentially leading to a denial of service. The attacker sends a | stream of headers with a 0-length header name and 0-length header | value, optionally Huffman encoded into 1-byte or greater headers. Some | implementations allocate memory for these headers and keep the | allocation alive until the session dies. This can consume excess | memory. If you fix the vulnerabilities please also make sure to include the CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
