Ubuntu Security Notice 6037-1 - ZeddYu Lu discovered that the FTP client from Apache Commons Net trusted the host from PASV responses by default. A remote attacker with a malicious FTP server could redirect the client to another server, which could possibly result in leaked information about services running on the private network of the client.

Ubuntu Security Notice 6046-1 - It was discovered that OpenSSL-ibmca incorrectly handled certain RSA decryption. An attacker could possibly use this issue to expose sensitive information.

Ubuntu Security Notice 6047-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed.

swfrender v0.9.2 was discovered to contain a heap buffer overflow in the function enumerateUsedIDs_fillstyle at modules/swftools.c

Ubuntu Security Notice 6042-1 - James Glovich discovered that sensitive data could be exposed in logs. An attacker could use this information to find hashed passwords and possibly escalate their privilege.

Ubuntu Security Notice 6045-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. Gwnaun Jung discovered that the SFB packet scheduling implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6044-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. It was discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6017-2 - USN-6017-1 fixed vulnerabilities in Ghostscript. This update provides the corresponding updates for Ubuntu 23.04. Hadrien Perrineau discovered that Ghostscript incorrectly handled certain inputs. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 6043-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for thisCVE, kernel support for the TCINDEX classifier has been removed. It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges.

Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege.
