CVE-2020-11080 6 Debian, Fedoraproject, Nghttp2 and 3 more 10 Debian Linux, Fedora, Nghttp2 and 7 more 2022-08-29 5.0 MEDIUM 7.5 HIGH
In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.
CVE-2020-1971 8 Debian, Fedoraproject, Netapp and 5 more 46 Debian Linux, Fedora, Active Iq Unified Manager and 43 more 2022-08-29 4.3 MEDIUM 5.9 MEDIUM
The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue. Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w).
CVE-2021-3449 12 Checkpoint, Debian, Fedoraproject and 9 more 167 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 164 more 2022-08-29 4.3 MEDIUM 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-2019-11047 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2022-08-29 6.4 MEDIUM 6.5 MEDIUM
When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what will cause it to read past the allocated buffer. This may lead to information disclosure or crash.
CVE-2020-10700 3 Fedoraproject, Opensuse, Samba 3 Fedora, Leap, Samba 2022-08-29 2.6 LOW 5.3 MEDIUM
A use-after-free flaw was found in the way samba AD DC LDAP servers, handled 'Paged Results' control is combined with the 'ASQ' control. A malicious user in a samba AD could use this flaw to cause denial of service. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2.
CVE-2015-3152 6 Debian, Fedoraproject, Mariadb and 3 more 12 Debian Linux, Fedora, Mariadb and 9 more 2022-08-29 4.3 MEDIUM 5.9 MEDIUM
Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before 5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack.
CVE-2019-19246 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2022-08-29 5.0 MEDIUM 7.5 HIGH
Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in str_lower_case_match in regexec.c.
CVE-2019-3880 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Leap and 3 more 2022-08-29 5.5 MEDIUM 5.4 MEDIUM
A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable.

CVE-2021-22924 6 Debian, Fedoraproject, Haxx and 3 more 52 Debian Linux, Fedora, Libcurl and 49 more 2022-08-28 4.3 MEDIUM 3.7 LOW
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
CVE-2018-14463 7 Apple, Debian, F5 and 4 more 7 Mac Os X, Debian Linux, Traffix Sdc and 4 more 2022-08-26 5.0 MEDIUM 7.5 HIGH
