Blue Coat Systems WinProxy 6.1a and 6.0 r1c, and possibly earlier, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a long HTTP CONNECT request, which triggers heap corruption.

Buffer overflow in k9filter.exe in BlueCoat K9 Web Protection 3.2.36, and probably other versions before 3.2.44, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP GET request to port 2372.

Cross-site scripting (XSS) vulnerability in the ICAP patience page in Blue Coat Security Gateway OS (SGOS) 4.2 before 4.2.9, 5.2 before 5.2.5, and 5.3 before 5.3.1.7 allows remote attackers to inject arbitrary web script or HTML via the URL.

dne2000.sys in Citrix Deterministic Network Enhancer (DNE) 2.21.7.233 through 3.21.7.17464, as used in (1) Cisco VPN Client, (2) Blue Coat WinProxy, and (3) SafeNet SoftRemote and HighAssurance Remote, allows local users to gain privileges via a crafted DNE_IOCTL DeviceIoControl request to the \\.\DNE device interface.

Blue Coat ProxySG, when transparent interception mode is enabled, uses the HTTP Host header to determine the remote endpoint, which allows remote attackers to bypass access controls for Flash, Java, Silverlight, and probably other technologies, and possibly communicate with restricted intranet sites, via a crafted web page that causes a client to send HTTP requests with a modified Host header.

Unknown vulnerability in Blue Coat Reporter before 7.1.2 allows remote unauthenticated attackers to add a license.

Multiple cross-site scripting (XSS) vulnerabilities in Blue Coat Reporter before 7.1.2 allow remote attackers to inject arbitrary web script or HTML via (1) the username in an Add User window or (2) the license key (volatile.license_to_add parameter) in the Licensing page.

The listening daemon in Blue Coat Systems Inc. WinProxy before 6.1a allows remote attackers to cause a denial of service (crash) via a long HTTP request that causes an out-of-bounds read.

Cross-site scripting (XSS) vulnerability in Blue Coat Systems (formerly CacheFlow) CacheOS on Client Accelerator 4.1.06, Security Gateway 2.1.02, and Server Accelerator 4.1.06 allows remote attackers to inject arbitrary web script or HTML via a URL to a nonexistent hostname that includes the HTML, which is inserted into the resulting error page.

Buffer overflow in BlueCoat (a) WinProxy before 6.1a and (b) the web console access functionality in ProxyAV before 2.4.2.3 allows remote attackers to execute arbitrary code via a long Host: header.

Blue Coat Proxy Security Gateway OS (SGOS) 4.1.2.1 does not enforce CONNECT rules when using Deep Content Inspection, which allows remote attackers to bypass connection filters.

Blue Coat Systems Inc. WinProxy before 6.1a allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large number of packets with 0xFF characters to the Telnet port (TCP 23), which corrupts the heap.

security flaw

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

security flaw

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.

security flaw

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.

templates.admin.users.user_form_processing in Blue Coat Reporter before 7.1.2 allows authenticated users to gain administrator privileges via an HTTP POST that sets volatile.user.administrator to true.

Blue Coat Advanced Secure Gateway (ASG) 6.6 before 6.6.5.4 and Content Analysis System (CAS) 1.3 before 1.3.7.4 are susceptible to an OS command injection vulnerability. An authenticated malicious administrator can execute arbitrary OS commands with elevated system privileges.

Symantec SSL Visibility (SSLV) 3.8.4FC, 3.9, 3.10 before 3.10.4.1, and 3.11 before 3.11.3.1 is susceptible to a denial-of-service vulnerability that impacts the SSL servers for intercepted SSL connections. A malicious SSL client can, under certain circumstances, temporarily exhaust the TCP connection pool of an SSL server.

Blue Coat Advanced Secure Gateway 6.6, CacheFlow 3.4, ProxySG 6.5 and 6.6 allows remote attackers to bypass blocked requests, user authentication, and payload scanning.

Blue Coat Unified Agent before 4.6.2 does not prevent modification of its configuration files when running in local enforcement mode, which allows local administrators to unblock categories or disable the agent via unspecified vectors.
