An issue was discovered in Pulse Secure Pulse Connect Secure (PCS) through 2020-04-06. The applet in tncc.jar, executed on macOS, Linux, and Solaris clients when a Host Checker policy is enforced, accepts an arbitrary SSL certificate.

XSS exists in the admin web console in Pulse Secure Pulse Connect Secure (PCS) 9.0RX before 9.0R3.4, 8.3RX before 8.3R7.1, and 8.1RX before 8.1R15.1 and Pulse Policy Secure 9.0RX before 9.0R3.2, 5.4RX before 5.4R7.1, and 5.2RX before 5.2R12.1.

In Pulse Secure Pulse Connect Secure version 9.0RX before 9.0R3.4, 8.3RX before 8.3R7.1, 8.2RX before 8.2R12.1, and 8.1RX before 8.1R15.1 and Pulse Policy Secure version 9.0RX before 9.0R3.2, 5.4RX before 5.4R7.1, 5.3RX before 5.3R12.1, 5.2RX before 5.2R12.1, and 5.1RX before 5.1R15.1, an authenticated attacker (via the admin web interface) can send a specially crafted message resulting in a stack buffer overflow.

In Pulse Secure Pulse Connect Secure version 9.0RX before 9.0R3.4, 8.3RX before 8.3R7.1, and 8.2RX before 8.2R12.1, users using SAML authentication with the Reuse Existing NC (Pulse) Session option may see authentication leaks.

In Pulse Secure Pulse Connect Secure version 9.0RX before 9.0R3.4 and 8.3RX before 8.3R7.1 and Pulse Policy Secure version 9.0RX before 9.0R3.2 and 5.4RX before 5.4R7.1, an unauthenticated, remote attacker can conduct a session hijacking attack.

In Pulse Secure Pulse Connect Secure (PCS) before 8.1R15.1, 8.2 before 8.2R12.1, 8.3 before 8.3R7.1, and 9.0 before 9.0R3.4, an authenticated attacker (via the admin web interface) can exploit Directory Traversal to execute arbitrary code on the appliance.

In Pulse Secure Pulse Desktop Client and Network Connect, an attacker could access session tokens to replay and spoof sessions, and as a result, gain unauthorized access as an end user, a related issue to CVE-2019-1573. (The endpoint would need to be already compromised for exploitation to succeed.) This affects Pulse Desktop Client 5.x before Secure Desktop 5.3R7 and Pulse Desktop Client 9.x before Secure Desktop 9.0R3. It also affects (for Network Connect customers) Pulse Connect Secure 8.1 before 8.1R14, 8.3 before 8.3R7, and 9.0 before 9.0R3.

Pulse Secure Pulse Connect Secure 8.1.x before 8.1R14, 8.2.x before 8.2R11, and 8.3.x before 8.3R5 do not properly process nested XML entities, which allows remote attackers to cause a denial of service (memory consumption and memory errors) via a crafted XML document.

A vulnerability has been discovered in login.cgi in Pulse Secure Pulse Connect Secure (PCS) 8.1RX before 8.1R12 and 8.3RX before 8.3R2 and Pulse Policy Secure (PPS) 5.2RX before 5.2R9 and 5.4RX before 5.4R2 wherein an http(s) Host header received from the browser is trusted without validation.

A stack-based Buffer Overflow Vulnerability exists in the web server in Pulse Secure Pulse Connect Secure (PCS) before 8.3R4 and Pulse Policy Secure (PPS) before 5.4R4, leading to memory corruption and possibly remote code execution.

ghostscript: 1Policy operator allows a sandbox protection bypass

Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving the 1Policy operator.

ghostscript: setcolor missing type check (699655)

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the setcolor function to crash the interpreter or possibly have unspecified other impact.

ghostscript: Uninitialized memory access in the aesdecode operator (699665)

In Artifex Ghostscript 9.23 before 2018-08-24, attackers able to supply crafted PostScript could use uninitialized memory access in the aesdecode operator to crash the interpreter or potentially execute code.

ghostscript: LockDistillerParams type confusion (699656)

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the LockDistillerParams parameter to crash the interpreter or execute code.

ghostscript: shading_param incomplete type checking (699660)

In Artifex Ghostscript 9.23 before 2018-08-24, a type confusion using the .shfill operator could be used by attackers able to supply crafted PostScript files to crash the interpreter or potentially execute code.

download.cgi in Pulse Secure Pulse Connect Secure 8.1RX before 8.1R13 and 8.3RX before 8.3R4 and Pulse Policy Secure through 5.2RX before 5.2R10 and 5.4RX before 5.4R4 have an Open Redirect Vulnerability.

A cross site scripting issue has been found in custompage.cgi in Pulse Secure Pulse Connect Secure (PCS) before 8.0R17.0, 8.1.x before 8.1R13, 8.2.x before 8.2R9, and 8.3.x before 8.3R3 and Pulse Policy Secure (PPS) before 5.2R10, 5.3.x before 5.3R9, and 5.4.x before 5.4R3 due to one of the URL parameters not being sanitized. Exploitation does require the user to be logged in as administrator; the issue is not applicable to the end user portal.
