![]() Memory leak in drivers/media/video/videobuf-core.c in the videobuf subsystem in the Linux kernel 2.6.x through 4.x allows local users to cause a denial of service (memory consumption) by leveraging /dev/video access for a series of mmap calls that require new allocations, a different vulnerability than CVE-2007-6761. Memory leak in the v9fs_xattrcreate function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) via a large number of Txattrcreate messages with the same fid number. Memory leak in the v9fs_write function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) by leveraging failure to free an IO vector. A guest user/process could use this issue to leak host memory, resulting in DoS for a host. It could occur while processing packet data in 'ehci_init_transfer'. Quick Emulator (Qemu) built with the USB EHCI Emulation support is vulnerable to a memory leakage issue. There is a memory leak in GfxColorSpace::setDisplayProfile in, as demonstrated by pdftocairo.ĥ Debian Linux, Qemu, Enterprise Linux and 2 more In the Linux kernel before 5.17.2, drivers/soc/qcom/qcom_aoss.c does not release an of_find_device_by_node reference after use, e.g., with put_device.Ĥ Canonical, Debian, Freedesktop and 1 moreġ0 Ubuntu Linux, Debian Linux, Poppler and 7 moreĪn issue was discovered in Poppler 0.71.0. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. In BIG-IP versions 17.0.x before 17.0.0.2, and 16.1.x beginning in 16.1.2.2 to before 16.1.3.3, when an HTTP profile is configured on a virtual server and conditions beyond the attacker’s control exist on the target pool member, undisclosed requests sent to the BIG-IP system can cause the Traffic Management Microkernel (TMM) to terminate. ![]() Connections using SSL/TLS are not taking this timeout into account during reads, and may hang longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers, resulting in a Denial of Service.ġ2 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 9 more However this timeout applies only for un-encrypted requests. Each sockets will be waited by the worker for at most 'ioblocktimeout' seconds. In 389-ds-base up to version 1.4.1.2, requests are handled by workers threads. A successful exploit could allow the attacker to exhaust the IP addresses from the assigned local pool, which prevents users from logging in and leads to a denial of service (DoS) condition.ģ Debian Linux, 389 Directory Server, Enterprise Linux An attacker could exploit this vulnerability by trying to connect to the device with a non-An圜onnect client. This vulnerability occurs because the code does not release the allocated IP address under certain failure conditions. A local authenticated administrator user could potentially exploit this vulnerability by consuming excess memory in order to cause the application to crash.Ģ77 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4p Integrated Services Router and 274 moreĪ vulnerability in the Internet Key Exchange Version 2 (IKEv2) support for the AutoReconnect feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to exhaust the free IP addresses from the assigned local pool. As a workaround, turn off URL preview functionality by setting `url_preview_enabled: false` in the Synapse configuration file.ĥ0 Chengming 3900, Chengming 3900 Firmware, Inspiron 14 Plus 7420 and 47 moreĭell BIOS versions contain a Missing Release of Resource after Effective Lifetime vulnerability. ![]() Upgrade to 1.53.0 to fully resolve the issue. Since generating URL previews for media streams is not supported and always fails, 1.53.0 additionally implements an allow list for content types for which Synapse will even attempt to generate a URL preview. Version 1.52.0 implements a timeout mechanism which will terminate URL preview connections after 30 seconds. This can cause excessive traffic and connections toward such servers if their stream URL is, for example, posted to a large room with many Synapse instances with URL preview enabled. ![]() Connections will only be terminated after `max_spider_size` (default: 10M) bytes have been downloaded, which can in some cases lead to long-lived connections towards the streaming media server (for instance, Icecast). Synapse before 1.52.0 with URL preview functionality enabled will attempt to generate URL previews for media stream URLs without properly limiting connection time. ![]()
