CVE-2024-12087 [HIGH] CWE-22 CVE-2024-12087: A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursi 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 o

CVE-2026-19550 [HIGH] CWE-863 CVE-2026-19550: A flaw was found in FreeIPA. The trust-fetch-domains command is gated by a read-only permission on t A flaw was found in FreeIPA. The trust-fetch-domains command is gated by a read-only permission on the trust object rather than a trust-administration permission, allowing an authenticated, non-privileged IPA user to trigger a privileged Active Directory trust refresh using an attacker-supplied server and credentials, resulting in unauthorized, attack

CVE-2021-3737 [HIGH] CWE-835 CVE-2021-3737: A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python ma A flaw was found in python.

CVE-2026-102560 [CRITICAL] CWE-125 CVE-2026-102560: A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.

CVE-2026-53002 [CRITICAL] CWE-787 CVE-2026-53002: In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: remove sp In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: remove sprintf usage Replace it with scnprintf, the buffer sizes are expected to be large enough to hold the result, no need for snprintf+overflow check. Increase buffer size in mangle_content_len() while at it. BUG: KASAN: stack-out-of-bounds in vsnprintf

CVE-2011-3630 [HIGH] CWE-787 CVE-2011-3630: Hardlink before 0.1.2 suffer from multiple stack-based buffer overflow flaws because of the way dire Hardlink before 0.1.2 suffer from multiple stack-based buffer overflow flaws because of the way directory trees with deeply nested directories are processed. A remote attacker could provide a specially-crafted directory tree, and trick the local user into consolidating it, leading to hardlink executable crash, or, potentially arbitrary code execution wi

CVE-2019-9503 [HIGH] CWE-20 CVE-2019-9503: The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulner The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source, the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver receives the firmware event frame from the

CVE-2017-15710 [HIGH] CWE-787 CVE-2017-15710: In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configur In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate

CVE-2004-0633 [MEDIUM] CVE-2004-0633: The iSNS dissector for Ethereal 0.10.3 through 0.10.4 allows remote attackers to cause a denial of s The iSNS dissector for Ethereal 0.10.3 through 0.10.4 allows remote attackers to cause a denial of service (process abort) via an integer overflow.
