This Secure Web Gateway release includes updates addressing publicly disclosed CVEs, regardless of whether a CVE has been shown to impact customers.
The following medium and higher-level CVEs (CVSS 3.0 >= 4) were involved:

CVE-2022-43680: In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate in out-of-memory situations.
CVE-2022-40982: Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
CVE-2023-22045: Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition, Oracle GraalVM for JDK product of Oracle Java SE (component: Hotspot). Supported versions that are affected are Oracle Java SE: 8u371, 8u371-perf, 11.0.19, 17.0.7, 20.0.1; Oracle GraalVM Enterprise Edition: 20.3.10, 21.3.6, 22.3.2; Oracle GraalVM for JDK: 17.0.7 and 20.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition, Oracle GraalVM for JDK. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Java SE, Oracle GraalVM Enterprise Edition, Oracle GraalVM for JDK accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 3.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).

CVE-2023-22049: \Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition, Oracle GraalVM for JDK product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 8u371, 8u371-perf, 11.0.19, 17.0.7, 20.0.1; Oracle GraalVM Enterprise Edition: 20.3.10, 21.3.6, 22.3.2; Oracle GraalVM for JDK: 17.0.7 and 20.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition, Oracle GraalVM for JDK. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition, Oracle GraalVM for JDK accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).

CVE-2023-22067: Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: CORBA). Supported versions that are affected are Oracle Java SE: 8u381, 8u381-perf; Oracle GraalVM Enterprise Edition: 20.3.11 and 21.3.7. Easily exploitable vulnerability allows unauthenticated attacker with network access via CORBA to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data.

CVE-2023-22081:
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u381, 8u381-perf, 11.0.20, 17.0.8, 21; Oracle GraalVM for JDK: 17.0.8, 21; Oracle GraalVM Enterprise Edition: 20.3.11, 21.3.7 and 22.3.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
CVE-2020-8616 A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches performed when processing referrals can, through the use of specially crafted referrals, cause a recursing server to issue a very large number of fetches in an attempt to process the referral. This has at least two potential effects: The performance of the recursing server can potentially be degraded by the additional work required to perform these fetches, and The attacker can exploit this behavior to use the recursing server as a reflector in a reflection attack with a high amplification factor.

CVE-2020-8625: BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11, and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition. Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch
CVE-2023-5388: It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether high order bits of the RSA decryption result are zero. This information can be used to mount a Bleichenbacher or Manger like attack against all RSA decryption operations. As the leak happens before any padding operations, it affects all padding modes: PKCS#1 v1.5, OAEP, and RSASVP. Both API level calls and TLS server operation are affected.
