Gentoo Linux Security Advisory GLSA 200409-26
Severity: Normal SynopsisNew releases of Mozilla, Epiphany, Mozilla Thunderbird, and Mozilla Firefox fix several vulnerabilities, including the remote execution of arbitrary code. BackgroundMozilla is a popular web browser that includes a mail and newsreader. Epiphany is a web browser that uses Gecko, the Mozilla rendering engine. Mozilla Firefox and Mozilla Thunderbird are respectively the next-generation browser and mail client from the Mozilla project. Affected packages
7 affected packages on all of their supported architectures. DescriptionMozilla-based products are vulnerable to multiple security issues. Firstly routines handling the display of BMP images and VCards contain an integer overflow and a stack buffer overrun. Specific pages with long links, when sent using the "Send Page" function, and links with non-ASCII hostnames could both cause heap buffer overruns. Several issues were found and fixed in JavaScript rights handling: untrusted script code could read and write to the clipboard, signed scripts could build confusing grant privileges dialog boxes, and when dragged onto trusted frames or windows, JavaScript links could access information and rights of the target frame or window. Finally, Mozilla-based mail clients (Mozilla and Mozilla Thunderbird) are vulnerable to a heap overflow caused by invalid POP3 mail server responses. ImpactAn attacker might be able to run arbitrary code with the rights of the user running the software by enticing the user to perform one of the following actions: view a specially-crafted BMP image or VCard, use the "Send Page" function on a malicious page, follow links with malicious hostnames, drag multiple JavaScript links in a row to another window, or connect to an untrusted POP3 mail server. An attacker could also use a malicious page with JavaScript to disclose clipboard contents or abuse previously-given privileges to request XPI installation privileges through a confusing dialog. WorkaroundThere is no known workaround covering all vulnerabilities. ResolutionAll users should upgrade to the latest stable version:
# emerge sync
# emerge -pv your-version
# emerge your-version

Severity: Normal SynopsisA vulnerability in CUPS allows remote attackers to cause a denial of service when sending a carefully-crafted UDP packet to the IPP port. BackgroundThe Common UNIX Printing System (CUPS) is a cross-platform print spooler. Affected packages
DescriptionAlvaro Martinez Echevarria discovered a hole in the CUPS Internet Printing Protocol (IPP) implementation that allows remote attackers to cause CUPS to stop listening on the IPP port. This can be caused by sending an empty UDP datagram packet to the IPP port. ImpactA remote user with malicious intent can easily cause a denial of service to the CUPS daemon. WorkaroundThere is no known workaround at this time. ResolutionAll CUPS users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-print/cups-1.1.20-r2"
# emerge ">=net-print/cups-1.1.20-r2"

Severity: High SynopsisThe foomatic-rip filter in foomatic-filters contains a vulnerability which may allow arbitrary command execution on the print server. BackgroundFoomatic is a system for connecting printer drivers with spooler systems such as CUPS and LPD. The foomatic-filters package contains wrapper scripts which are designed to be used with Foomatic. Affected packages
2 affected packages on all of their supported architectures. DescriptionThere is a vulnerability in the foomatic-filters package. This vulnerability is due to insufficient checking of command-line parameters and environment variables in the foomatic-rip filter. ImpactThis vulnerability may allow both local and remote attackers to execute arbitrary commands on the print server with the permissions of the spooler (oftentimes the "lp" user). WorkaroundThere is no known workaround at this time. ResolutionAll foomatic users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-print/foomatic-3.0.2"
# emerge ">=net-print/foomatic-3.0.2"
PLEASE NOTE: You should update foomatic, instead of foomatic-filters. This will help to ensure that all other foomatic components remain functional.
