CVE-2021-26566 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 6.8 MEDIUM 9.0 CRITICAL
Insertion of sensitive information into sent data vulnerability in synorelayd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to execute arbitrary commands via inbound QuickConnect traffic.
CVE-2019-9518 11 Apache, Apple, Canonical and 8 more 20 Traffic Server, Mac Os X, Swiftnio and 17 more 2025-01-14 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-2019-9517 12 Apache, Apple, Canonical and 9 more 25 Http Server, Traffic Server, Mac Os X and 22 more 2025-01-14 7.8 HIGH 7.5 HIGH
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 bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.
CVE-2019-9515 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2025-01-14 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-2019-19344 4 Canonical, Opensuse, Samba and 1 more 7 Ubuntu Linux, Leap, Samba and 4 more 2025-01-14 4.0 MEDIUM 6.5 MEDIUM
There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer.
CVE-2019-9516 12 Apache, Apple, Canonical and 9 more 21 Traffic Server, Mac Os X, Swiftnio and 18 more 2025-01-14 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-2018-1160 3 Debian, Netatalk, Synology 7 Debian Linux, Netatalk, Diskstation Manager and 4 more 2025-01-14 10.0 HIGH 9.8 CRITICAL
Netatalk before 3.1.12 is vulnerable to an out of bounds write in dsi_opensess.c. This is due to lack of bounds checking on attacker controlled data. A remote unauthenticated attacker can leverage this vulnerability to achieve arbitrary code execution.
CVE-2018-13281 1 Synology 3 Diskstation Manager, Skynas, Vs960hd 2025-01-14 4.0 MEDIUM 4.3 MEDIUM
Information exposure vulnerability in SYNO.Core.ACL in Synology DiskStation Manager (DSM) before 6.2-23739-2 allows remote authenticated users to determine the existence and obtain the metadata of arbitrary files via the file_path parameter.
CVE-2018-8897 8 Apple, Canonical, Citrix and 5 more 11 Mac Os X, Ubuntu Linux, Xenserver and 8 more 2019-10-03 7.2 HIGH 7.8 HIGH
A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.
