CVE-2025-5987 2 Libssh, Redhat 6 Libssh, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-03-05 8.1 High
A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with the SSH_OK code, resulting in libssh not properly detecting the error returned by the OpenSSL library. This issue can lead to undefined behavior, including compromised data confidentiality and integrity or crashes.
CVE-2023-5870 2 Postgresql, Redhat 22 Postgresql, Advanced Cluster Security, Codeready Linux Builder Eus and 19 more 2026-03-02 2.2 Low
A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.

CVE-2025-59089 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-01-28 5.9 Medium
If an attacker causes kdcproxy to connect to an attacker-controlled KDC server (e.g. through server-side request forgery), they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copies the entire buffered stream into a new buffer on each recv() call, even when the transfer is incomplete, causing excessive memory allocation and CPU usage. Additionally, kdcproxy accepts incoming response chunks as long as the received data length is not exactly equal to the length indicated in the response header, even when individual chunks or the total buffer exceed the maximum length of a Kerberos message. This allows an attacker to send unbounded data until the connection timeout is reached (approximately 12 seconds), exhausting server memory or CPU resources. Multiple concurrent requests can cause accept queue overflow, denying service to legitimate clients.
CVE-2024-12088 8 Almalinux, Archlinux, Gentoo and 5 more 21 Almalinux, Arch Linux, Linux and 18 more 2026-01-28 6.5 Medium
A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.
CVE-2024-12087 8 Almalinux, Archlinux, Gentoo and 5 more 26 Almalinux, Arch Linux, Linux and 23 more 2026-01-28 6.5 Medium
A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.
CVE-2023-47038 3 Fedoraproject, Perl, Redhat 5 Fedora, Perl, Enterprise Linux and 2 more 2026-01-22 7 High
A vulnerability was found in perl 5.30.0 through 5.38.0. This issue occurs when a crafted regular expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer.
CVE-2013-0648 7 Adobe, Apple, Linux and 4 more 12 Flash Player, Mac Os X, Linux Kernel and 9 more 2026-01-12 8.8 High

CVE-2025-59088 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2025-12-19 8.6 High
If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request for a realm matching a DNS zone where they created SRV records pointing to arbitrary ports and hostnames (which may resolve to loopback or internal IP addresses). This vulnerability can be exploited to probe internal network topology and firewall rules, perform port scanning, and exfiltrate data. Deployments where the "use_dns" setting is explicitly set to false are not affected.
