GLSA 200412-25: CUPS: Multiple vulnerabilities
| Severity: | high |
| Title: | CUPS: Multiple vulnerabilities |
| Date: | 12/28/2004 |
| Bugs: | , , |
| ID: | 200412-25 |
Synopsis
Multiple vulnerabilities have been found in CUPS, ranging from local Denial of Service attacks to the remote execution of arbitrary code.Background
The Common UNIX Printing System (CUPS) is a cross-platform print spooler, hpgltops is a CUPS filter handling printing of HPGL files and lppasswd is a program used locally to manage spooler passwords.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| net-print/cups | < 1.1.23 | >= 1.1.23 | All supported architectures |
Description
CUPS makes use of vulnerable Xpdf code to handle PDF files (CAN-2004-1125). Furthermore, Ariel Berkman discovered a buffer overflow in the ParseCommand function in hpgl-input.c in the hpgltops program (CAN-2004-1267). Finally, Bartlomiej Sieka discovered several problems in the lppasswd program: it ignores some write errors (CAN-2004-1268), it can leave the passwd.new file in place (CAN-2004-1269) and it does not verify that passwd.new file is different from STDERR (CAN-2004-1270).
Impact
The Xpdf and hpgltops vulnerabilities may be exploited by a remote attacker to execute arbitrary code by sending specific print jobs to a CUPS spooler. The lppasswd vulnerabilities may be exploited by a local attacker to write data to the CUPS password file or deny further password modifications.
Workaround
There is no known workaround at this time.
Resolution
All CUPS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/cups-1.1.23"
