An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to gain more privileges in a system.
CVE-2021-23214 3 Fedoraproject, Postgresql, Redhat 6 Fedora, Postgresql, Enterprise Linux and 3 more 2026-06-17 5.1 MEDIUM 8.1 HIGH
When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.
CVE-2021-23177 4 Debian, Fedoraproject, Libarchive and 1 more 13 Debian Linux, Fedora, Libarchive and 10 more 2026-06-17 N/A 7.8 HIGH
An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL of a file on the system and gain more privileges.
CVE-2021-20257 4 Debian, Fedoraproject, Qemu and 1 more 8 Debian Linux, Fedora, Qemu and 5 more 2026-06-17 2.1 LOW 6.5 MEDIUM
An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-9490 7 Apache, Canonical, Debian and 4 more 25 Http Server, Ubuntu Linux, Debian Linux and 22 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.
CVE-2020-8945 3 Fedoraproject, Gpgme Project, Redhat 10 Fedora, Gpgme, Enterprise Linux and 7 more 2026-06-17 5.1 MEDIUM 7.5 HIGH

CVE-2019-7317 11 Canonical, Debian, Hp and 8 more 33 Ubuntu Linux, Debian Linux, Xp7 Command View and 30 more 2026-06-17 2.6 LOW 5.3 MEDIUM
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.
CVE-2019-6470 3 Isc, Opensuse, Redhat 19 Dhcpd, Leap, Enterprise Linux and 16 more 2026-06-17 5.0 MEDIUM 6.5 MEDIUM
There had existed in one of the ISC BIND libraries a bug in a function that was used by dhcpd when operating in DHCPv6 mode. There was also a bug in dhcpd relating to the use of this function per its documentation, but the bug in the library function prevented this from causing any harm. All releases of dhcpd from ISC contain copies of this, and other, BIND libraries in combinations that have been tested prior to release and are known to not present issues like this. Some third-party packagers of ISC software have modified the dhcpd source, BIND source, or version matchup in ways that create the crash potential. Based on reports available to ISC, the crash probability is large and no analysis has been done on how, or even if, the probability can be manipulated by an attacker. Affects: Builds of dhcpd versions prior to version 4.4.1 when using BIND versions 9.11.2 or later, or BIND versions with specific bug fixes backported to them. ISC does not have access to comprehensive version lists for all repackagings of dhcpd that are vulnerable. In particular, builds from other vendors may also be affected. Operators are advised to consult their vendor documentation.
CVE-2019-5544 4 Fedoraproject, Openslp, Redhat and 1 more 16 Fedora, Openslp, Enterprise Linux Desktop and 13 more 2026-06-17 7.5 HIGH 9.8 CRITICAL

CVE-2019-19906 8 Apache, Apple, Canonical and 5 more 20 Bookkeeper, Ipados, Iphone Os and 17 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.
CVE-2019-13272 6 Canonical, Debian, Fedoraproject and 3 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2026-06-17 7.2 HIGH 7.8 HIGH
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.
CVE-2019-11043 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2026-06-17 7.5 HIGH 8.7 HIGH
In PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24 and 7.3.x below 7.3.11 in certain configurations of FPM setup it is possible to cause FPM module to write past allocated buffers into the space reserved for FCGI protocol data, thus opening the possibility of remote code execution.
CVE-2019-0211 8 Apache, Canonical, Debian and 5 more 27 Http Server, Ubuntu Linux, Debian Linux and 24 more 2026-06-17 7.2 HIGH 7.8 HIGH
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.
CVE-2018-16881 3 Debian, Redhat, Rsyslog 13 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 10 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0 are vulnerable.
CVE-2017-15129 4 Canonical, Fedoraproject, Linux and 1 more 20 Ubuntu Linux, Fedora, Linux Kernel and 17 more 2026-06-17 4.9 MEDIUM 4.7 MEDIUM
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.
