CVSS v3.1 |
| Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows local users with lp privileges to create or overwrite arbitrary files via file race conditions, as demonstrated by ice-cream. |
| jobs.c in Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly use the strncat function call when processing the options string, which allows remote attackers to execute arbitrary code via a buffer overflow attack. |
| Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows remote attackers to add printers without authentication via a certain UDP packet, which can then be used to perform unauthorized activities such as stealing the local root certificate for the administration server via a "need authorization" page, as demonstrated by new-coke. |
| filters/image-gif.c in Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly check for zero-length GIF images, which allows remote attackers to execute arbitrary code via modified chunk headers, as demonstrated by nogif. |
| Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly check the return values of various file and socket operations, which could allow a remote attacker to cause a denial of service (resource exhaustion) by causing file descriptors to be assigned and not released, as demonstrated by fanta. |
| Multiple integer overflows in Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allow remote attackers to execute arbitrary code via (1) the CUPSd HTTP interface, as demonstrated by vanilla-coke, and (2) the image handling code in CUPS filters, as demonstrated by mksun. |
| OpenPrinting CUPS is a standards-based, open source printing system for Linux and other Unix-like operating systems. Starting in version 2.0.0 and prior to version 2.4.6, CUPS logs data of free memory to the logging service AFTER the connection has been closed, when it should have logged the data right before. This is a use-after-free bug that impacts the entire cupsd process.
The exact cause of this issue is the function `httpClose(con->http)` being called in `scheduler/client.c`. The problem is that httpClose always, provided its argument is not null, frees the pointer at the end of the call, only for cupsdLogClient to pass the pointer to httpGetHostname. This issue happens in function `cupsdAcceptClient` if LogLevel is warn or higher and in two scenarios: there is a double-lookup for the IP Address (HostNameLookups Double is set in `cupsd.conf`) which fails to resolve, or if CUPS is compiled with TCP wrappers and the connection is refused by rules from `/etc/hosts.allow` and `/etc/hosts.deny`.
Version 2.4.6 has a patch for this issue. |
| A logic issue was addressed with improved state management. This issue is fixed in Security Update 2022-003 Catalina, macOS Monterey 12.3, macOS Big Sur 11.6.5. An application may be able to gain elevated privileges. |
| The session cookie generated by the CUPS web interface was easy to guess on Linux, allowing unauthorized scripted access to the web interface when the web interface is enabled. This issue affected versions prior to v2.2.10. |
| The add_job function in scheduler/ipp.c in CUPS before 2.2.6, when D-Bus support is enabled, can be crashed by remote attackers by sending print jobs with an invalid username, related to a D-Bus notification. |
| A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1). |
| cups (Common Unix Printing System) 'Listen localhost:631' option not honored correctly which could provide unauthorized access to the system |
