rejetto HFS (aka HTTP File Server) v2.3m Build #300, when virtual files or folders are used, allows remote attackers to trigger an invalid-pointer write access violation via concurrent HTTP requests with a long URI or long HTTP headers.

Dell BSAFE Micro Edition Suite, versions prior to 4.5, are vulnerable to a Buffer Under-Read Vulnerability. An unauthenticated remote attacker could potentially exploit this vulnerability resulting in undefined behaviour, or a crash of the affected systems.

Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).

Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: Web Listener). The supported version that is affected is 11.1.1.9.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle HTTP Server. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle HTTP Server accessible data as well as unauthorized read access to a subset of Oracle HTTP Server accessible data. CVSS 3.0 Base Score 6.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N).

In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL.

In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server.

Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: OSSL Module). Supported versions that are affected are 11.1.1.9.0, 12.1.3.0.0 and 12.2.1.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle HTTP Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle HTTP Server. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: Web Listener). Supported versions that are affected are 11.1.1.9.0, 12.1.3.0.0 and 12.2.1.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle HTTP Server. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle HTTP Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle HTTP Server accessible data as well as unauthorized read access to a subset of Oracle HTTP Server accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

Static HTTP Server 1.0 has a Local Overflow

A Path traversal exists in http_server which allows an attacker to read arbitrary system files.
