Mandrake Linux Security Advisory : mozilla (MDKSA-2005:088)

High Nessus Plugin ID 18277


The remote Mandrake Linux host is missing one or more security updates.


A number of security vulnerabilities were fixed in the Mozilla Firefox 1.0.4 and Mozilla Suite 1.7.8 releases. Patches have been backported where appropriate; Corporate 3.0 is receiving the new Mozilla Suite 1.7.8 release.

The following issues have been fixed in both Mozilla Firefox and Mozilla Suite :

- A flaw in the JavaScript regular expression handling could lead to a disclosure of browser memory, potentially exposing private data from web pages viewed, passwords, or similar data sent to other web pages. It could also crash the browser itself (CVE-2005-0989, MFSA 2005-33)

- With manual Plugin install, it was possible for the Plugin to execute JavaScript code with the installing user's privileges (CVE-2005-0752 and MFSA 2005-34)

- The popup for showing blocked JavaScript used the wrong privilege context which could be sued for privilege escalation (CVE-2005-1153 and MFSA 2005-35)

- Cross-site scripting through global scope pollution could lead an attacker to being able to run code in foreign websites context, leading to the potential sniffing of information or performing actions in that context (CVE-2005-1154 and MFSA 2005-36)

- Code execution through JavaScript via favicons ('firelinking') could be used for privilege escalation (CVE-2005-1155 and MFSA 2005-37)

- Search plugin cross-site scripting ('firesearching') (CVE-2005-1156, CVE-2005-1157, and MFSA 2005-38)

- Arbitrary code execution via the Firefox sidebar panel II (CVE-2005-1158 and MFSA 2005-39)

- Missing Install object instance checks (CVE-2005-1159 and MFSA 2005-40)

- Privilege escalation via DOM property overrides (CVE-2005-1160 and MFSA 2005-41)

- Code execution via javacript: IconURL (MFSA 2005-42)

- Security check bypass by wrapping a javascript: URL in the view-source: pseudo protocol (MFSA 2005-43)

- Privilege escalation via non-DOM property overrides (MFSA 2005-44)

In addition to the vulnerabilities previously noted, the following issues have been fixed in the Mozilla Suite 1.7.2 packages :

- Bypass restriction on opening privileged XUL (CVE-2005-0401 and MSF 2005-32)

- Arbitrary code execution via a GIF processing error when parsing obsolete Netscape extension 2 leading to an exploitable heap overrun (CVE-2005-0401 and MFSA 2005-32)

- International Domain Name support could allow for characters that look similar to other english letters to be used in constructing nearly perfect phishing sites (MFSA 2005-29)

- Predictable plugin temporary directory name (MFSA 2005-28)

- Plugins can be used to load privileged content into a frame (CVE-2005-0527 and MFSA 2005-27)

- Cross-site scripting attack via dropping javascript:
links on a tab (MFSA 2005-26)

- Image dragging-and-drop from a web page to the desktop preserve their original name and extension; if this were an executable extension then the file would be executed rather than opened in a media application (MFSA 2005-25)

- HTTP authentication prompt tab spoofing (MFSA 2005-24)

- Download dialog source can be disguised by using a host name long enough that most significant parts are truncated, allowing a malicious site to spoof the origin of the file (MFSA 2005-23)

- Download dialog spoofing via supplied Content-Disposition header could allow for a file to look like a safe file (ie. a JPEG image) and when downloaded saved with an executable extension (MFSA 2005-22)

- XSLT can include stylesheets from arbitrary hosts (MFSA 2005-20)

- Memory handling flaw in Mozilla string classes that could overwrite memory at a fixed location if reallocation fails during string growth (MFSA 2005-18)

- Install source spoofing with user:[email protected] (MFSA 2005-17)

- Spoofing download and security dialogs with overlapping windows (MFSA 2005-16)

- It is possible for a UTF8 string with invalid sequences to trigger a heap overflow of converted Unicode data (MFSA 2005-15)

- SSL 'secure site' indicator spoofing (MFSA 2005-14)

- Mozilla mail clients responded to cookie requests accompanying content loaded over HTTP, ignoring the setting of the preference 'network.cookie.disableCookieForMailNews' which could be used to track people (MFSA 2005-11)

- Browser responds to proxy authentication requests from non-proxy servers (SSL/HTTPS) (MFSA 2005-09)

- Snythetic middle-click event can steal clipboard contents (MFSA 2005-08)

- In windows with multiple tabs, malicious content in a background tab can attempt to steal information intended for the topmost tab by popping up a prompt dialog that appears to come from the trusted site, or by silently redirecting input focus to a background tab hoping to catch the user inputting something sensitive (MFSA 2005-05)

- Secure site lock can be spoofed with 'view-source:' (MFSA 2005-04)

- An insecure page triggering a load of a binary file from a secure server will cause the SSL lock icon to appear;
the certificate information is that of the binary file's host and the location bar URL shows the original insecure page (MFSA 2005-03)

- Temporary files are saved with world-readable permissions (MFSA 2005-02)

- A vulnerability in the NNTP handling code could cause a heap overflow and execute arbitrary code on the client machine (isec-0020)

- A number of other minor bugs were fixed as well.

Mandriva recommends all users to upgrade to these packages immediately.
