A carefully crafted or corrupt sqlite file can cause an infinite loop in Apache Tika's SQLite3Parser in versions 1.8-1.19.1 of Apache Tika.

A shortcoming in the HMEF package of poi-scratchpad (Apache POI) allows an attacker to cause an Out of Memory exception. This package is used to read TNEF files (Microsoft Outlook and Microsoft Exchange Server). If an application uses poi-scratchpad to parse TNEF files and the application allows untrusted users to supply them, then a carefully crafted file can cause an Out of Memory exception. This issue affects poi-scratchpad version 5.2.0 and prior versions. Users are recommended to upgrade to poi-scratchpad 5.2.1.

The BPG parser in versions of Apache Tika before 1.28.2 and 2.4.0 may allocate an unreasonable amount of memory on carefully crafted files.

In Apache PDFBox 1.8.0 to 1.8.15 and 2.0.0RC1 to 2.0.11, a carefully crafted PDF file can trigger an extremely long running computation when parsing the page tree.

A carefully crafted or corrupt PSD file can cause excessive memory usage in Apache Tika's PSDParser in versions 1.0-1.23.

A carefully crafted or corrupt PSD file can cause an infinite loop in Apache Tika's PSDParser in versions 1.0-1.23.

Subversion's mod_authz_svn module will crash if the server is using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option and a client sends a request for a non-existing repository URL. This can lead to disruption for users of the service. This issue was fixed in mod_dav_svn+mod_authz_svn servers 1.14.1 and mod_dav_svn+mod_authz_svn servers 1.10.7

A specially crafted ZIP archive can be used to cause an infinite loop inside of Apache Commons Compress' extra field parser used by the ZipFile and ZipArchiveInputStream classes in versions 1.11 to 1.15. This can be used to mount a denial of service attack against services that use Compress' zip package.

The mod_proxy_ajp module in the Apache HTTP Server before 2.2.21, when used with mod_proxy_balancer in certain configurations, allows remote attackers to cause a denial of service (temporary "error state" in the backend server) via a malformed HTTP request.

Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.

http/conn/ssl/SSLConnectionSocketFactory.java in Apache HttpComponents HttpClient before 4.3.6 ignores the http.socket.timeout configuration setting during an SSL handshake, which allows remote attackers to cause a denial of service (HTTPS call hang) via unspecified vectors.

A carefully crafted PDF file can trigger an infinite loop while loading the file. This issue affects Apache PDFBox version 2.0.22 and prior 2.0.x versions.

The cache_invalidate function in modules/cache/cache_storage.c in the mod_cache module in the Apache HTTP Server 2.4.6, when a caching forward proxy is enabled, allows remote HTTP servers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger a missing hostname value.
