RHSA-2004:421 - Security Advisory
Synopsis
mozilla security update
Type/Severity
Security Advisory: Critical
Topic
Updated mozilla packages based on version 1.4.3 that fix a number of
security issues for Red Hat Enterprise Linux are now available.
Description
Mozilla is an open source Web browser, advanced email and newsgroup
client, IRC chat client, and HTML editor.
A number of flaws have been found in Mozilla 1.4 that have been fixed in
the Mozilla 1.4.3 release:
Zen Parse reported improper input validation to the SOAPParameter object
constructor leading to an integer overflow and controllable heap
corruption. Malicious JavaScript could be written to utilize this flaw and
could allow arbitrary code execution. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0722 to
this issue.
During a source code audit, Chris Evans discovered a buffer overflow and
integer overflows which affect the libpng code inside Mozilla. An attacker
could create a carefully crafted PNG file in such a way that it would cause
Mozilla to crash or execute arbitrary code when the image was viewed.
(CAN-2004-0597, CAN-2004-0599)
Zen Parse reported a flaw in the POP3 capability. A malicious POP3 server
could send a carefully crafted response that would cause a heap overflow
and potentially allow execution of arbitrary code as the user running
Mozilla. (CAN-2004-0757)
Marcel Boesch found a flaw that allows a CA certificate to be imported with
a DN the same as that of the built-in CA root certificates, which can cause
a denial of service to SSL pages, as the malicious certificate is treated
as invalid. (CAN-2004-0758)
Met - Martin Hassman reported a flaw in Mozilla that could allow malicious
Javascript code to upload local files from a users machine without
requiring confirmation. (CAN-2004-0759)
Mindlock Security reported a flaw in ftp URI handling. By using a NULL
character (%00) in a ftp URI, Mozilla can be confused into opening a
resource as a different MIME type. (CAN-2004-0760)
Mozilla does not properly prevent a frame in one domain from injecting
content into a frame that belongs to another domain, which facilitates
website spoofing and other attacks, also known as the frame injection
vulnerability. (CAN-2004-0718)
Tolga Tarhan reported a flaw that can allow a malicious webpage to use a
redirect sequence to spoof the security lock icon that makes a webpage
appear to be encrypted. (CAN-2004-0761)
Jesse Ruderman reported a security issue that affects a number of browsers
including Mozilla that could allow malicious websites to install arbitrary
extensions by using interactive events to manipulate the XPInstall Security
dialog box. (CAN-2004-0762)
Emmanouel Kellinis discovered a caching flaw in Mozilla which allows
malicious websites to spoof certificates of trusted websites via
redirects and Javascript that uses the "onunload" method. (CAN-2004-0763)
Mozilla allowed malicious websites to hijack the user interface via the
"chrome" flag and XML User Interface Language (XUL) files. (CAN-2004-0764)
The cert_TestHostName function in Mozilla only checks the hostname portion
of a certificate when the hostname portion of the URI is not a fully
qualified domain name (FQDN). This flaw could be used for spoofing if an
attacker had control of machines on a default DNS search path. (CAN-2004-0765)
All users are advised to update to these erratum packages which contain a
snapshot of Mozilla 1.4.3 including backported fixes and are not vulnerable
to these issues.
