McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9517, potentially leading to a denial of service. This affects the scanning proxies.

McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9511, potentially leading to a denial of service. This affects the scanning proxies.

Administrative Server in Micro Focus Host Access Management and Security Server (MSS) and Reflection for the Web (RWeb) and Reflection Security Gateway (RSG) and Reflection ZFE (ZFE) allows remote unauthenticated attackers to read arbitrary files via a specially crafted URL that allows limited directory traversal. Applies to MSS 12.3 before 12.3.326 and MSS 12.2 before 12.2.342 and RSG 12.1 before 12.1.362 and RWeb 12.3 before 12.3.312 and RWeb 12.2 before 12.2.342 and RWeb 12.1 before 12.1.362 and ZFE 2.0.1 before 2.0.1.18 and ZFE 2.0.0 before 2.0.0.52 and ZFE 1.4.0 before 1.4.0.14.

Heap-based buffer overflow in the Decomposer component in multiple Symantec products allows remote attackers to execute arbitrary code via multiple crafted CAB archives.

The Decomposer component in multiple Symantec products allows remote attackers to cause a denial of service (infinite loop) via a certain value in the PACK_SIZE field of a RAR archive file header.

The proxy DNS service in Symantec Gateway Security (SGS) allows remote attackers to make arbitrary DNS queries to third-party DNS servers, while hiding the source IP address of the attacker. NOTE: another researcher has stated that the default configuration does not proxy DNS queries received on the external interface

The HTTP proxy in Symantec Gateway Security 5000 Series 2.0.1 and 3.0, and Enterprise Firewall 8.0, when NAT is being used, allows remote attackers to determine internal IP addresses by using malformed HTTP requests, as demonstrated using a get request without a space separating the URI.

Buffer overflow in the Internet Key Exchange version 1 (IKEv1) implementation in Symantec Dynamic VPN Services, as used in Enterprise Firewall, Gateway Security, and Firewall /VPN Appliance products, allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1.

The Sun Java Plugin capability in Java 2 Runtime Environment (JRE) 1.4.2_01, 1.4.2_04, and possibly earlier versions, does not properly restrict access between Javascript and Java applets during data transfer, which allows remote attackers to load unsafe classes and execute arbitrary code by using the reflection API to access private Java packages.

Heap-based buffer overflow in the DEC2EXE module for Symantec AntiVirus Library allows remote attackers to execute arbitrary code via a UPX compressed file containing a negative virtual offset to a crafted PE header.
