CVE-2019-3856 7 Debian, Fedoraproject, Libssh2 and 4 more 17 Debian Linux, Fedora, Libssh2 and 14 more 2026-10-14 8.8 High
An integer overflow flaw, which could lead to an out of bounds write, was discovered in libssh2 before 1.8.1 in the way keyboard prompt requests are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-3855 8 Apple, Debian, Fedoraproject and 5 more 18 Xcode, Debian Linux, Fedora and 15 more 2026-10-14 8.8 High
An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-19126 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-10-14 3.3 Low
On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
CVE-2019-17498 6 Debian, Fedoraproject, Libssh2 and 3 more 13 Debian Linux, Fedora, Libssh2 and 10 more 2026-10-14 8.1 High
In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server.
CVE-2019-16168 9 Canonical, Debian, Fedoraproject and 6 more 21 Ubuntu Linux, Debian Linux, Fedora and 18 more 2026-10-14 6.5 Medium
In SQLite through 3.29.0, whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application because of missing validation of a sqlite_stat1 sz field, aka a "severe division by zero in the query planner."
CVE-2019-16056 7 Canonical, Debian, Fedoraproject and 4 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2026-10-14 5.3 Medium
An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An application that uses the email module and implements some kind of checks on the From/To headers of a message could be tricked into accepting an email address that should be denied. An attack may be the same as in CVE-2019-11340; however, this CVE applies to Python more generally.
CVE-2019-10160 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2026-10-14 9.8 Critical
A security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.
CVE-2018-20843 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2026-10-14 7.5 High
In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).
CVE-2015-20107 4 Fedoraproject, Netapp, Python and 1 more 7 Fedora, Active Iq Unified Manager, Ontap Select Deploy Administration Utility and 4 more 2026-10-14 7.8 High
In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9
CVE-2013-4235 3 Debian, Fedoraproject, Redhat 4 Debian Linux, Shadow, Fedora and 1 more 2026-10-14 4.7 Medium
shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees
CVE-2023-30589 3 Fedoraproject, Nodejs, Redhat 4 Fedora, Node.js, Enterprise Linux and 1 more 2026-10-08 7.5 High
The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS). The CR character (without LF) is sufficient to delimit HTTP header fields in the llhttp parser. According to RFC7230 section 3, only the CRLF sequence should delimit each header-field. This impacts all Node.js active versions: v16, v18, and, v20
CVE-2023-2269 5 Debian, Fedoraproject, Linux and 2 more 14 Debian Linux, Fedora, Linux Kernel and 11 more 2026-10-08 4.4 Medium
A denial of service problem was found, due to a possible recursive locking scenario, resulting in a deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-component.
CVE-2023-20900 7 Debian, Fedoraproject, Linux and 4 more 12 Debian Linux, Fedora, Linux Kernel and 9 more 2026-10-08 7.1 High
A malicious actor that has been granted Guest Operation Privileges https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-security/GUID-6A952214-0E5E-4CCF-9D2A-90948FF643EC.html  in a target virtual machine may be able to elevate their privileges if that target virtual machine has been assigned a more privileged Guest Alias https://vdc-download.vmware.com/vmwb-repository/dcr-public/d1902b0e-d479-46bf-8ac9-cee0e31e8ec0/07ce8dbd-db48-4261-9b8f-c6d3ad8ba472/vim.vm.guest.AliasManager.html .
CVE-2022-21986 3 Fedoraproject, Microsoft, Redhat 6 Fedora, .net, Visual Studio 2019 and 3 more 2026-10-08 7.5 High

CVE-2022-0500 4 Fedoraproject, Linux, Netapp and 1 more 21 Fedora, Linux Kernel, H300e and 18 more 2026-10-08 7.8 High
A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system.
CVE-2021-43975 5 Debian, Fedoraproject, Linux and 2 more 21 Debian Linux, Fedora, Linux Kernel and 18 more 2026-10-08 6.7 Medium
In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value.
CVE-2021-3449 13 Checkpoint, Debian, Fedoraproject and 10 more 172 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 169 more 2026-10-08 5.9 Medium
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).
CVE-2020-11987 5 Apache, Debian, Fedoraproject and 2 more 23 Batik, Debian Linux, Fedora and 20 more 2026-10-08 8.2 High
Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the NodePickerPanel. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.
CVE-2020-11979 5 Apache, Fedoraproject, Gradle and 2 more 38 Ant, Fedora, Gradle and 35 more 2026-10-08 7.5 High
As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
CVE-2019-20445 6 Apache, Canonical, Debian and 3 more 20 Spark, Ubuntu Linux, Debian Linux and 17 more 2026-10-08 9.1 Critical
HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header.
