All supported architectures
Multiple vulnerabilities have been found in HPLIP, the worst of
which may allow execution of arbitrary code.
The Hewlett-Packard Linux Imaging and Printing system (HPLIP) provides
drivers for HP's inkjet and laser printers, scanners and fax machines.
Two vulnerabilities have been found in HPLIP:
- The "hpmud_get_pml()" function in pml.c contains a boundary error
which could cause a stack-based buffer overflow (CVE-2010-4267).
- The "send_data_to_stdout()" function in hpcupsfax.cpp creates
insecure temporary files (CVE-2011-2722).
A remote attacker might send specially crafted SNMP reponses, possibly
resulting in execution of arbitrary code or a Denial of Service
condition. Furthermore, a local attacker could perform symlink attacks to
overwrite arbitrary files.
There is no known workaround at this time.
All HPLIP users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/hplip-3.11.10"
