Description
This security bulletin contains information about 2 vulnerabilities.
1) Argument injection (CVE-ID: CVE-2026-105326)
CWE-ID: CWE-88 - Argument Injection or Modification
CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to execute arbitrary code with the privileges of the filter user (lp).
The vulnerability exists due to argument injection in the mailto notifier's pipe_sendmail function in notifier/mailto.c when passing subscription recipient addresses to sendmail. A local user can create a printer subscription with a crafted notify-recipient-uri that causes sendmail to load an attacker-controlled configuration file to execute arbitrary code with the privileges of the filter user (lp).
Exploitation requires traditional sendmail with support for the -C option and a subscribed event to trigger notification delivery.
2) Out-of-bounds read (CVE-ID: CVE-2026-41079)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 5.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to out-of-bounds read in the CUPS SNMP backend when processing crafted SNMP responses during supply-level polling. A remote attacker can send a specially crafted SNMP response to disclose sensitive information.
The leaked memory is converted from UTF-16 to UTF-8 and becomes visible to authenticated users via IPP Get-Printer-Attributes responses and the CUPS web interface. Exploitation requires an SNMP-discovered printer on the same LAN segment.
