CVE-2020-29479 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2026-06-17 7.2 HIGH 8.8 HIGH
An issue was discovered in Xen through 4.14.x. In the Ocaml xenstored implementation, the internal representation of the tree has special cases for the root node, because this node has no parent. Unfortunately, permissions were not checked for certain operations on the root node. Unprivileged guests can get and modify permissions, list, and delete the root node. (Deleting the whole xenstore tree is a host-wide denial of service.) Achieving xenstore write access is also possible. All systems using oxenstored are vulnerable. Building and using oxenstored is the default in the upstream Xen distribution, if the Ocaml compiler is available. Systems using C xenstored are not vulnerable.
CVE-2020-29443 2 Debian, Qemu 2 Debian Linux, Qemu 2026-06-17 3.3 LOW 3.9 LOW
ide_atapi_cmd_reply_end in hw/ide/atapi.c in QEMU 5.1.0 allows out-of-bounds read access because a buffer index is not validated.
CVE-2020-29394 2 Debian, Genivi 2 Debian Linux, Diagnostic Log And Trace 2026-06-17 6.8 MEDIUM 7.8 HIGH
A buffer overflow in the dlt_filter_load function in dlt_common.c from dlt-daemon through 2.18.5 (GENIVI Diagnostic Log and Trace) allows arbitrary code execution because fscanf is misused (no limit on the number of characters to be read in the format argument).
CVE-2020-29260 2 Debian, Libvncserver Project 2 Debian Linux, Libvncserver 2026-06-17 N/A 7.5 HIGH
libvncclient v0.9.13 was discovered to contain a memory leak via the function rfbClientCleanup().
CVE-2020-29130 3 Debian, Fedoraproject, Libslirp Project 3 Debian Linux, Fedora, Libslirp 2026-06-17 4.0 MEDIUM 4.3 MEDIUM
slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
CVE-2020-29129 3 Debian, Fedoraproject, Libslirp Project 3 Debian Linux, Fedora, Libslirp 2026-06-17 4.0 MEDIUM 4.3 MEDIUM
ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
CVE-2020-29074 3 Debian, Fedoraproject, X11vnc Project 3 Debian Linux, Fedora, X11vnc 2026-06-17 6.5 MEDIUM 8.8 HIGH
scan.c in x11vnc 0.9.16 uses IPC_CREAT|0777 in shmget calls, which allows access by actors other than the current user.
CVE-2020-29050 2 Debian, Sphinxsearch 2 Debian Linux, Sphinx 2026-06-17 5.0 MEDIUM 7.5 HIGH
SphinxSearch in Sphinx Technologies Sphinx through 3.1.1 allows directory traversal (in conjunction with CVE-2019-14511) because the mysql client can be used for CALL SNIPPETS and load_file operations on a full pathname (e.g., a file in the /etc directory). NOTE: this is unrelated to CMUSphinx.
CVE-2020-28984 2 Debian, Spip 2 Debian Linux, Spip 2026-06-17 7.5 HIGH 9.8 CRITICAL
prive/formulaires/configurer_preferences.php in SPIP before 3.2.8 does not properly validate the couleur, display, display_navigation, display_outils, imessage, and spip_ecran parameters.
CVE-2020-28974 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-06-17 6.1 MEDIUM 5.0 MEDIUM
A slab-out-of-bounds read in fbcon in the Linux kernel before 5.9.7 could be used by local attackers to read privileged information or potentially crash the kernel, aka CID-3c4e0dff2095. This occurs because KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height.
CVE-2020-28972 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
In SaltStack Salt before 3002.5, authentication to VMware vcenter, vsphere, and esxi servers (in the vmware.py files) does not always validate the SSL/TLS certificate.
CVE-2020-28949 4 Debian, Drupal, Fedoraproject and 1 more 4 Debian Linux, Drupal, Fedora and 1 more 2026-06-17 6.8 MEDIUM 7.8 HIGH
Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed.
CVE-2020-28948 4 Debian, Drupal, Fedoraproject and 1 more 4 Debian Linux, Drupal, Fedora and 1 more 2026-06-17 6.8 MEDIUM 7.8 HIGH
Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not blocked.
CVE-2020-28941 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in drivers/accessibility/speakup/spk_ttyio.c in the Linux kernel through 5.9.9. Local attackers on systems with the speakup driver could cause a local denial of service attack, aka CID-d41227544427. This occurs because of an invalid free when the line discipline is used more than once.
CVE-2020-28935 2 Debian, Nlnetlabs 3 Debian Linux, Name Server Daemon, Unbound 2026-06-17 2.1 LOW 5.5 MEDIUM
NLnet Labs Unbound, up to and including version 1.12.0, and NLnet Labs NSD, up to and including version 4.3.3, contain a local vulnerability that would allow for a local symlink attack. When writing the PID file, Unbound and NSD create the file if it is not there, or open an existing file for writing. In case the file was already present, they would follow symlinks if the file happened to be a symlink instead of a regular file. An additional chown of the file would then take place after it was written, making the user Unbound/NSD is supposed to run as the new owner of the file. If an attacker has local access to the user Unbound/NSD runs as, she could create a symlink in place of the PID file pointing to a file that she would like to erase. If then Unbound/NSD is killed and the PID file is not cleared, upon restarting with root privileges, Unbound/NSD will rewrite any file pointed at by the symlink. This is a local vulnerability that could create a Denial of Service of the system Unbound/NSD is running on. It requires an attacker having access to the limited permission user Unbound/NSD runs as and point through the symlink to a critical file on the system.
CVE-2020-28928 4 Debian, Fedoraproject, Musl-libc and 1 more 4 Debian Linux, Fedora, Musl and 1 more 2026-06-17 2.1 LOW 5.5 MEDIUM
In musl libc through 1.2.1, wcsnrtombs mishandles particular combinations of destination buffer size and source character limit, as demonstrated by an invalid write access (buffer overflow).
CVE-2020-28926 2 Debian, Readymedia Project 2 Debian Linux, Readymedia 2026-06-17 7.5 HIGH 9.8 CRITICAL
ReadyMedia (aka MiniDLNA) before versions 1.3.0 allows remote code execution. Sending a malicious UPnP HTTP request to the miniDLNA service using HTTP chunked encoding can lead to a signedness bug resulting in a buffer overflow in calls to memcpy/memmove.
CVE-2020-28916 2 Debian, Qemu 2 Debian Linux, Qemu 2026-06-17 2.1 LOW 5.5 MEDIUM
hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop via an RX descriptor with a NULL buffer address.
CVE-2020-28896 3 Debian, Mutt, Neomutt 3 Debian Linux, Mutt, Neomutt 2026-06-17 2.6 LOW 5.3 MEDIUM
Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle.
CVE-2020-28636 3 Cgal, Debian, Fedoraproject 3 Computational Geometry Algorithms Library, Debian Linux, Fedora 2026-06-17 7.5 HIGH 9.8 CRITICAL
A code execution vulnerability exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. An oob read vulnerability exists in Nef_S2/SNC_io_parser.h SNC_io_parser::read_sloop() slh->twin() An attacker can provide malicious input to trigger this vulnerability.
