Denial of service in Apache Struts
CVE-2014-0050

Infinite loop

The vulnerability allows a remote attacker to cause DoS conditions on the target system.

The weakness exists due to boundary error when handling Content-Type HTTP header for multipart requests. By sending a specially crafted Content-Type header, containing 4092 characters in "boundary" field, a remote attacker can cause the application to enter into an infinite loop.

Successful exploitation of the vulnerability results in denial of service on the vulnerable system.

Note: the vulnerability was being actively exploited.

Denial of service in Apache HTTP Server
CVE-2011-3192

Resource exhaustion

The vulnerability allows a remote attacker to cause DoS conditions on the target system.

Successful exploitation of the vulnerability results in denial service on the vulnerable system.

Note: the vulnerability was being actively exploited.

Denial of service in Apache Subversion
CVE-2011-1752

Null pointer dereference

The vulnerability allows a remote attacker to cause DoS conditions on the target system.

The weakness exists due to NULL pointer dereference in the mod_dav_svn module when processing baselined WebDAV resources. A remote attacker can create a specially crafted request, send it to the victim and cause the Subversion server to crash.

Successful exploitation of the vulnerability results in denial of service on the vulnerable system.

Note: the vulnerability was being actively exploited.

About zero-day vulnerabilities

Zero-day vulnerability is an undisclosed vulnerability in software that hackers can exploit to compromise computer programs, gain unauthorized access to sensitive data, penetrate networks, etc. We consider vulnerability a zero-day when there is no solution provided from software vendor and the vulnerability is being actively exploited by malicious actors.

Zero-day candidate is a potential zero-day vulnerability in software which might have been used in targeted attacks, however there is no evidence to support this suggestion.
