CVE-2019-6454 8 Canonical, Debian, Fedoraproject and 5 more 22 Ubuntu Linux, Debian Linux, Fedora and 19 more 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).
CVE-2019-6251 6 Canonical, Fedoraproject, Gnome and 3 more 6 Ubuntu Linux, Fedora, Epiphany and 3 more 2026-06-17 5.8 MEDIUM 8.1 HIGH
WebKitGTK and WPE WebKit prior to version 2.24.1 are vulnerable to address bar spoofing upon certain JavaScript redirections. An attacker could cause malicious web content to be displayed as if for a trusted URI. This is similar to the CVE-2018-8383 issue in Microsoft Edge.
CVE-2019-6215 3 Apple, Canonical, Microsoft 8 Icloud, Iphone Os, Itunes and 5 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
A type confusion issue was addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2019-6212 3 Apple, Canonical, Microsoft 7 Icloud, Iphone Os, Itunes and 4 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2019-6133 4 Canonical, Debian, Polkit Project and 1 more 9 Ubuntu Linux, Debian Linux, Polkit and 6 more 2026-06-17 4.4 MEDIUM 6.7 MEDIUM
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.
CVE-2019-6128 4 Canonical, Debian, Libtiff and 1 more 4 Ubuntu Linux, Debian Linux, Libtiff and 1 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
The TIFFFdOpen function in tif_unix.c in LibTIFF 4.0.10 has a memory leak, as demonstrated by pal2rgb.
CVE-2019-6116 6 Artifex, Canonical, Debian and 3 more 11 Ghostscript, Ubuntu Linux, Debian Linux and 8 more 2026-06-17 6.8 MEDIUM 7.8 HIGH
In Artifex Ghostscript through 9.26, ephemeral or transient procedures can allow access to system operators, leading to remote code execution.
CVE-2019-5882 2 Canonical, Irssi 2 Ubuntu Linux, Irssi 2026-06-17 7.5 HIGH 9.8 CRITICAL
Irssi 1.1.x before 1.1.2 has a use after free when hidden lines are expired from the scroll buffer.
CVE-2019-5827 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
Integer overflow in SQLite via WebSQL in Google Chrome prior to 74.0.3729.131 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
CVE-2019-5798 6 Canonical, Debian, Google and 3 more 7 Ubuntu Linux, Debian Linux, Chrome and 4 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
Lack of correct bounds checking in Skia in Google Chrome prior to 73.0.3683.75 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.
CVE-2019-5747 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP client, server, and/or relay) might allow a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679.
CVE-2019-5736 13 Apache, Canonical, D2iq and 10 more 19 Mesos, Ubuntu Linux, Dc\/os and 16 more 2026-06-17 9.3 HIGH 8.6 HIGH
runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.
CVE-2019-5477 3 Canonical, Debian, Nokogiri 3 Ubuntu Linux, Debian Linux, Nokogiri 2026-06-17 7.5 HIGH 9.8 CRITICAL
A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess via Ruby's `Kernel.open` method. Processes are vulnerable only if the undocumented method `Nokogiri::CSS::Tokenizer#load_file` is being called with unsafe user input as the filename. This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.
CVE-2019-5108 5 Canonical, Debian, Linux and 2 more 21 Ubuntu Linux, Debian Linux, Linux Kernel and 18 more 2026-06-17 3.3 LOW 6.5 MEDIUM
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.
CVE-2019-5068 4 Canonical, Debian, Mesa3d and 1 more 4 Ubuntu Linux, Debian Linux, Mesa and 1 more 2026-06-17 3.6 LOW 4.4 MEDIUM
An exploitable shared memory permissions vulnerability exists in the functionality of X11 Mesa 3D Graphics Library 19.1.2. An attacker can access the shared memory without any specific permissions to trigger this vulnerability.
CVE-2019-5052 4 Canonical, Debian, Libsdl and 1 more 5 Ubuntu Linux, Debian Linux, Sdl2 Image and 2 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
An exploitable integer overflow vulnerability exists when loading a PCX file in SDL2_image 2.0.4. A specially crafted file can cause an integer overflow, resulting in too little memory being allocated, which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
CVE-2019-5051 4 Canonical, Debian, Libsdl and 1 more 5 Ubuntu Linux, Debian Linux, Sdl2 Image and 2 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
An exploitable heap-based buffer overflow vulnerability exists when loading a PCX file in SDL2_image, version 2.0.4. A missing error handler can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
CVE-2019-3900 7 Canonical, Debian, Fedoraproject and 4 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2026-06-17 6.8 MEDIUM 7.7 HIGH
An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.
CVE-2019-3887 4 Canonical, Fedoraproject, Linux and 1 more 11 Ubuntu Linux, Fedora, Linux Kernel and 8 more 2026-06-17 4.7 MEDIUM 5.6 MEDIUM
A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash the host kernel resulting in DoS issue. Kernel versions from 4.16 and newer are vulnerable to this issue.
CVE-2019-3885 3 Canonical, Clusterlabs, Fedoraproject 3 Ubuntu Linux, Pacemaker, Fedora 2026-06-17 5.0 MEDIUM 3.3 LOW
A use-after-free flaw was found in pacemaker up to and including version 2.0.1 which could result in certain sensitive information to be leaked via the system logs.
