CVE-2019-20919 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2026-06-17 1.9 LOW 4.7 MEDIUM
An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference.

An issue was discovered in drivers/firmware/efi/efi.c in the Linux kernel before 5.4. Incorrect access permissions for the efivar_ssdt ACPI variable could be used by attackers to bypass lockdown or secure boot restrictions, aka CID-1957a85b0032.
CVE-2019-20840 5 Canonical, Debian, Libvnc Project and 2 more 16 Ubuntu Linux, Debian Linux, Libvncserver and 13 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in LibVNCServer before 0.9.13. libvncserver/ws_decode.c can lead to a crash because of unaligned accesses in hybiReadAndDecode.
CVE-2019-20839 5 Canonical, Debian, Libvnc Project and 2 more 16 Ubuntu Linux, Debian Linux, Libvncserver and 13 more 2026-06-17 5.0 MEDIUM 7.5 HIGH

An issue was discovered in the Linux kernel before 5.0.6. In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.
CVE-2019-20810 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c in the Linux kernel before 5.6 does not call snd_card_free for a failure path, which causes a memory leak, aka CID-9453264ef586.
CVE-2019-20807 6 Apple, Canonical, Debian and 3 more 7 Mac Os X, Ubuntu Linux, Debian Linux and 4 more 2026-06-17 4.6 MEDIUM 5.3 MEDIUM
In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands via scripting interfaces (e.g., Python, Ruby, or Lua).
CVE-2019-20788 4 Canonical, Debian, Libvnc Project and 1 more 15 Ubuntu Linux, Debian Linux, Libvncserver and 12 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
libvncclient/cursor.c in LibVNCServer through 0.9.12 has a HandleCursorShape integer overflow and heap-based buffer overflow via a large height or width value. NOTE: this may overlap CVE-2019-15690.
CVE-2019-20503 3 Canonical, Debian, Usrsctp Project 3 Ubuntu Linux, Debian Linux, Usrsctp 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
usrsctp before 2019-12-20 has out-of-bounds reads in sctp_load_addresses_from_init.
CVE-2019-20446 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
In xml.rs in GNOME librsvg before 2.46.2, a crafted SVG file with nested patterns can cause denial of service when passed to the library for processing. The attacker constructs pattern elements so that the number of final rendered objects grows exponentially.
CVE-2019-20421 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2026-06-17 7.8 HIGH 7.5 HIGH
In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.
CVE-2019-20386 5 Canonical, Fedoraproject, Netapp and 2 more 7 Ubuntu Linux, Fedora, Active Iq Unified Manager and 4 more 2026-06-17 2.1 LOW 2.4 LOW
An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur.
CVE-2019-20382 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2026-06-17 2.7 LOW 3.5 LOW
QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd.
CVE-2019-20372 5 Apple, Canonical, F5 and 2 more 5 Xcode, Ubuntu Linux, Nginx and 2 more 2026-06-17 4.3 MEDIUM 5.3 MEDIUM
NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.
CVE-2019-20096 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b.

The autocmd feature in window.c in Vim before 8.1.2136 accesses freed memory.
CVE-2019-1999 3 Canonical, Debian, Google 3 Ubuntu Linux, Debian Linux, Android 2026-06-17 7.2 HIGH 7.8 HIGH
In binder_alloc_free_page of binder_alloc.c, there is a possible double free due to improper locking. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-120025196.
CVE-2019-1559 13 Canonical, Debian, F5 and 10 more 90 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 87 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).
CVE-2019-19949 4 Canonical, Debian, Imagemagick and 1 more 4 Ubuntu Linux, Debian Linux, Imagemagick and 1 more 2026-06-17 6.4 MEDIUM 9.1 CRITICAL

CVE-2019-19948 4 Canonical, Debian, Imagemagick and 1 more 4 Ubuntu Linux, Debian Linux, Imagemagick and 1 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
In ImageMagick 7.0.8-43 Q16, there is a heap-based buffer overflow in the function WriteSGIImage of coders/sgi.c.
