Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2018-0732)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to improper handling of large prime values by the affected software during key agreement operations in a Transport Layer Security (TLS) handshake using an Ephemeral Diffie-Hellman (DHE) based cipher suite. A remote attacker can send a large prime value from a malicious OpenSSL server to a targeted OpenSSL client and cause the client to stop responding while generating a key for the prime value.
2) Cross-site scripting (CVE-ID: CVE-2015-9251)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when a cross-domain Ajax request is performed without the dataType option. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary text/javascript responses in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Deserialization of untrusted data (CVE-ID: CVE-2018-8013)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to insufficient validation of user-supplied data. A remote attacker can supply specially crafted data, trigger a deserialization error in a subclass of 'AbstractDocuent' and access potentially sensitive information.
4) Information disclosure (CVE-ID: CVE-2017-0379)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
Libgcrypt before 1.8.1 does not properly consider Curve25519 side-channel attacks, which makes it easier for attackers to discover a secret key, related to cipher/ecc.c and mpi/ec.c.
5) Heap-based buffer overflow (CVE-ID: CVE-2018-1000300)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to heap-based buffer overflow when closing down an FTP connection with very long server command replies. When doing FTP transfers, curl keeps a spare "closure handle" around internally that will be used when an FTP connection gets shut down since the original curl easy handle is then already removed. FTP server response data that gets cached from the original transfer might then be larger than the default buffer size (16 KB) allocated in the "closure handle", which can lead to buffer overwrite. A remote attacker can execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
6) Improper input validation (CVE-ID: CVE-2018-1000180)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the IDIH Visualization (Bouncy Castle Java Library) component in Oracle Communications Diameter Signaling Router (DSR). A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
7) Improper input validation (CVE-ID: CVE-2016-1181)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation in ActionServlet.java when handling multithreaded access to an ActionForm instance. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
8) Deserialization of untrusted data (CVE-ID: CVE-2017-5645)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists receiving serialized log events from another application when using the TCP socket server or UDP socket server. A remote attacker can submit a specially crafted binary payload, when deserialized, and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
