CVE-2023-50868 [HIGH] CWE-400 CVE-2023-50868: The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC responses in a random subdomain attack, aka the "NSEC3" issue. The RFC 5155 specification implies that an algorithm must perform thousands of iter

CVE-2019-9511 [HIGH] CWE-400 CVE-2019-9511: Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization man Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks.

CVE-2008-1767 [HIGH] CWE-119 CVE-2008-1767: Buffer overflow in pattern.c in libxslt before 1.1.24 allows context-dependent attackers to cause a Buffer overflow in pattern.c in libxslt before 1.1.24 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via an XSL style sheet file with a long XSLT "transformation match" condition that triggers a large number of steps.

CVE-2011-2767 [CRITICAL] CWE-94 CVE-2011-2767: mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user- mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context

CVE-2026-42055 [HIGH] CWE-122 CVE-2026-42055: NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_proxy_v2_module and ngx_http_g NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_proxy_v2_module and ngx_http_grpc_module modules. This vulnerability exists when the proxy_http_version to 2 or grpc_pass directives are used to proxy HTTP/2 traffic, the ignore_invalid_headers directive is set to off, and the large_client_header_buffers directive size is larger tha

CVE-2023-5869 [HIGH] CWE-190 CVE-2023-5869: A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code th A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbit

CVE-2021-3518 [HIGH] CWE-416 CVE-2021-3518: There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted fil There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free.
