Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2016-2183)
The vulnerability allows a remote attacker to decrypt transmitted data.
The vulnerability exists due to remote user's ability to control the network and capture long duration 3DES CBC mode encrypted session during which he can see a part of the text. In case of repeated sending the attacker can read the part and reconstruct the whole text.
Successful exploitation of this vulnerability may allow a remote attacker to decode transmitted data. This vulnerability is known as SWEET32.
2) Remote code execution (CVE-ID: CVE-2017-12615)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in Apache Tomcat when running on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) due to input validation flaw. A remote attacker can send a specially crafted HTTP PUT request to upload an arbitrary JSP file to the target system and request the file to execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
3) Improper input validation (CVE-ID: CVE-2017-12617)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to insufficient validation of user-supplied input when running with HTTP PUTs enabled. A remote attacker can send a specially crafted request to upload a JSP file to the server and execute arbitrary code on the system.
Successful exploitation of the vulnerability may result in full system compromise.
4) Information disclosure (CVE-ID: CVE-2017-9788)
The vulnerability allows a remote unauthenticated attacker to obtain potentially sensitive information on the targeted system.The weakness exists due to improper initialization of the value placeholder in [Proxy-]Authorization headers of type 'Digest' before or between successive key=value assignments by mod_auth_digest. A remote attacker can provide an initial key with no '=' assignment to cause the stale value of uninitialized pool memory used by the prior request to leak.
Successful exploitation of the vulnerability results in information disclosure.
5) Use-after-free (CVE-ID: CVE-2017-9798)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to use-after-free error when processing HTTP OPTIONS requests in server/core.c, when limits are configured in .htaccess or httpd.conf configuration files. A remote unauthenticated attacker can read portions of memory through HTTP OPTIONS requests and gain access to potentially sensitive data.
The vulnerability is dubbed Optionsbleed.
