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.
CVE-2019-3882 6 Canonical, Debian, Fedoraproject and 3 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.
CVE-2019-3878 4 Canonical, Fedoraproject, Mod Auth Mellon Project and 1 more 10 Ubuntu Linux, Fedora, Mod Auth Mellon and 7 more 2026-06-17 6.8 MEDIUM 8.1 HIGH
A vulnerability was found in mod_auth_mellon before v0.14.2. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication.
CVE-2019-3877 4 Canonical, Fedoraproject, Mod Auth Mellon Project and 1 more 4 Ubuntu Linux, Fedora, Mod Auth Mellon and 1 more 2026-06-17 4.3 MEDIUM 5.8 MEDIUM
A vulnerability was found in mod_auth_mellon before v0.14.2. An open redirect in the logout URL allows requests with backslashes to pass through by assuming that it is a relative URL, while the browsers silently convert backslash characters into forward slashes treating them as an absolute URL. This mismatch allows an attacker to bypass the redirect URL validation logic in apr_uri_parse function.
CVE-2019-3874 5 Canonical, Debian, Linux and 2 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2026-06-17 3.3 LOW 6.5 MEDIUM
The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable.
