CVE-2008-5183

Status Candidate

Overview

cupsd in CUPS 1.3.9 and earlier allows local users, and possibly remote attackers, to cause a denial of service (daemon crash) by adding a large number of RSS Subscriptions, which triggers a NULL pointer dereference. NOTE: this issue can be triggered remotely by leveraging CVE-2008-5184.

Debian Linux Security Advisory 2176-1 - Several vulnerabilities have been discovered in the Common UNIX Printing System. A null pointer dereference in RSS job completion notifications could lead to denial of service. It was discovered that incorrect file descriptor handling could lead to denial of service. A cross-site request forgery vulnerability was discovered in the web interface. Incorrect memory management in the filter subsystem could lead to denial of service. Emmanuel Bouillon discovered a symlink vulnerability in handling of cache files. Various other issues were also addressed.

Mandriva Linux Security Advisory 2009-028

Mandriva Linux Security Advisory 2009-028 - Security vulnerabilities have been discovered and corrected in CUPS. CUPS before 1.3.8 allows local users, and possibly remote attackers, to cause a denial of service (daemon crash) by adding a large number of RSS Subscriptions, which triggers a NULL pointer dereference. The web interface (cgi-bin/admin.c) in CUPS before 1.3.8 uses the guest username when a user is not logged on to the web server, which makes it easier for remote attackers to bypass intended policy and conduct CSRF attacks via the (1) add and (2) cancel RSS subscription functions. CUPS 1.1.17 through 1.3.9 allows remote attackers to execute arbitrary code via a PNG image with a large height value, which bypasses a validation check and triggers a buffer overflow. CUPS shipped with Mandriva Linux allows local users to overwrite arbitrary files via a symlink attack on the /tmp/pdf.log temporary file. The updated packages have been patched to prevent this.

Ubuntu Security Notice 707-1
Posted Jan 12, 2009
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice USN-707-1 - It was discovered that CUPS didn't properly handle adding a large number of RSS subscriptions. A local user could exploit this and cause CUPS to crash, leading to a denial of service. This issue only applied to Ubuntu 7.10, 8.04 LTS and 8.10. It was discovered that CUPS did not authenticate users when adding and cancelling RSS subscriptions. An unprivileged local user could bypass intended restrictions and add a large number of RSS subscriptions. This issue only applied to Ubuntu 7.10 and 8.04 LTS. It was discovered that the PNG filter in CUPS did not properly handle certain malformed images. If a user or automated system were tricked into opening a crafted PNG image file, a remote attacker could cause a denial of service or execute arbitrary code with user privileges. In Ubuntu 7.10, 8.04 LTS, and 8.10, attackers would be isolated by the AppArmor CUPS profile. It was discovered that the example pstopdf CUPS filter created log files in an insecure way. Local users could exploit a race condition to create or overwrite files with the privileges of the user invoking the program. This issue only applied to Ubuntu 6.06 LTS, 7.10, and 8.04 LTS.
