This Metasploit module exploits vulnerabilities in OpenPrinting CUPS, which is running by default on most Linux distributions. The vulnerabilities allow an attacker on the LAN to advertise a malicious printer that triggers remote code execution when a victim sends a print job to the malicious printer. Successful exploitation requires user interaction, but no CUPS services need to be reachable via accessible ports. Code execution occurs in the context of the lp user. Affected versions are cups-browsed less than or equal to 2.0.1, libcupsfilters versions 2.1b1 and below, libppd versions 2.1b1 and below, and cups-filters versions 2.0.1 and below.

Qualys discovered that needrestart suffers from multiple local privilege escalation vulnerabilities that allow for root access from an unprivileged user.

Ubuntu Security Notice 7015-6 - USN-7015-5 fixed vulnerabilities in python2.7. The update introduced several minor regressions. This update fixes the problem. It was discovered that the Python email module incorrectly parsed email addresses that contain special characters. A remote attacker could possibly use this issue to bypass certain protection mechanisms. It was discovered that Python allowed excessive backtracking while parsing certain tarfile headers. A remote attacker could possibly use this issue to cause Python to consume resources, leading to a denial of service. It was discovered that the Python email module incorrectly quoted newlines for email headers. A remote attacker could possibly use this issue to perform header injection. It was discovered that the Python http.cookies module incorrectly handled parsing cookies that contained backslashes for quoted characters. A remote attacker could possibly use this issue to cause Python to consume resources, leading to a denial of...

Ubuntu Security Notice 7120-3 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7118-1 - It was discovered that ZBar did not properly handle certain QR codes. If a user or automated system using ZBar were tricked into opening a specially crafted file, an attacker could possibly use this to obtain sensitive information. It was discovered that ZBar did not properly handle certain QR codes. If a user or automated system using ZBar were tricked into opening a specially crafted file, an attacker could possibly use this to obtain sensitive information. This issue only affected Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS.

Ubuntu Security Notice 7091-2 - USN-7091-1 fixed several vulnerabilities in Ruby. This update provides the corresponding update for ruby2.7 in Ubuntu 20.04 LTS. It was discovered that Ruby incorrectly handled parsing of an XML document that has specific XML characters in an attribute value using REXML gem. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service. This issue only affected in Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. It was discovered that Ruby incorrectly handled parsing of an XML document that has many entity expansions with SAX2 or pull parser API. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service. It was discovered that Ruby incorrectly handled parsing of an XML document that has many digits in a hex numeric character reference. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service.

Ubuntu Security Notice 7123-1 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service or possibly expose sensitive information. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code.
