CVE-2021-3156 8 Beyondtrust, Debian, Fedoraproject and 5 more 27 Privilege Management For Mac, Privilege Management For Unix\/linux, Debian Linux and 24 more 2022-09-02 7.2 HIGH 7.8 HIGH
Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character.
CVE-2019-9511 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2022-08-12 7.8 HIGH 7.5 HIGH
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 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2022-08-12 7.8 HIGH 7.5 HIGH
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-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2022-08-12 7.8 HIGH 7.5 HIGH
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.
CVE-2019-9518 11 Apache, Apple, Canonical and 8 more 20 Traffic Server, Mac Os X, Swiftnio and 17 more 2022-08-12 7.8 HIGH 7.5 HIGH
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 PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
CVE-2019-9515 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2022-08-12 7.8 HIGH 7.5 HIGH
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 equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2022-27616 1 Synology 1 Diskstation Manager 2022-08-10 N/A 7.2 HIGH
Improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in webapi component in Synology DiskStation Manager (DSM) before 7.0.1-42218-3 allows remote authenticated users to execute arbitrary commands via unspecified vectors.
CVE-2022-27617 1 Synology 2 Calendar, Diskstation Manager 2022-08-09 N/A 4.3 MEDIUM
Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in webapi component in Synology Calendar before 2.3.4-0631 allows remote authenticated users to download arbitrary files via unspecified vectors.
CVE-2022-27618 1 Synology 2 Diskstation Manager, Storage Analyzer 2022-08-09 N/A 6.5 MEDIUM
Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in webapi component in Synology Storage Analyzer before 2.1.0-0390 allows remote authenticated users to delete arbitrary files via unspecified vectors.
CVE-2022-27619 1 Synology 1 Note Station 2022-08-09 N/A 5.9 MEDIUM
Cleartext transmission of sensitive information vulnerability in authentication management in Synology Note Station Client before 2.2.2-609 allows man-in-the-middle attackers to obtain sensitive information via unspecified vectors.
CVE-2022-27620 1 Synology 2 Diskstation Manager, Sso Server 2022-08-09 N/A 4.9 MEDIUM
Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in webapi component in Synology SSO Server before 2.2.3-0331 allows remote authenticated users to read arbitrary files via unspecified vectors.
CVE-2022-27621 1 Synology 2 Diskstation Manager, Usb Copy 2022-08-09 N/A 3.8 LOW
Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in webapi component in Synology USB Copy before 2.2.0-1086 allows remote authenticated users to read or write arbitrary files via unspecified vectors.
CVE-2019-9516 12 Apache, Apple, Canonical and 9 more 21 Traffic Server, Mac Os X, Swiftnio and 18 more 2022-08-05 6.8 MEDIUM 6.5 MEDIUM
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.
CVE-2022-27615 1 Synology 1 Dns Server 2022-08-03 N/A 8.1 HIGH
Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in cgi component in Synology DNS Server before 2.2.2-5027 allows remote authenticated users to delete arbitrary files via unspecified vectors.
CVE-2022-22683 1 Synology 3 Diskstation Manager, Media Server, Router Manager 2022-08-03 N/A 9.8 CRITICAL
Buffer copy without checking size of input ('Classic Buffer Overflow') vulnerability in cgi component in Synology Media Server before 1.8.1-2876 allows remote attackers to execute arbitrary code via unspecified vectors.
