From technical-alerts@us-cert.gov Sun Sep 19 04:27:00 2004 From: US-CERT Technical Alerts To: technical-alerts@us-cert.gov Date: Fri, 17 Sep 2004 16:11:08 -0400 Subject: US-CERT Technical Cyber Security Alert TA04-261A -- Multiple vulnerabilities in Mozilla products -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Technical Cyber Security Alert TA04-261A Multiple vulnerabilities in Mozilla products Original release date: September 17, 2004 Last revised: -- Source: US-CERT Systems Affected Mozilla software, including the following: * Mozilla web browser, email and newsgroup client * Firefox web browser * Thunderbird email client Overview Several vulnerabilities exist in the Mozilla web browser and derived products, the most serious of which could allow a remote attacker to execute arbitrary code on an affected system. I. Description Several vulnerabilities have been reported in the Mozilla web browser and derived products. More detailed information is available in the individual vulnerability notes: VU#414240 - Mozilla Mail vulnerable to buffer overflow via writeGroup() function in nsVCardObj.cpp Mozilla Mail contains a stack overflow vulnerability in the display routines for VCards. By sending an email message with a crafted VCard, a remote attacker may be able to execute arbitrary code on the victim's machine with the privileges of the current user. This can be exploited in the preview mode as well. VU#847200 - Mozilla contains integer overflows in bitmap image decoder A vulnerability in the way Mozilla and its derived programs handle certain bitmap images could allow a remote attacker to execute arbitrary code on a vulnerable system. VU#808216 - Mozilla contains heap overflow in UTF8 conversion of hostname portion of URLs A vulnerability in the way Mozilla and its derived programs handle certain malformed URLs could allow a remote attacker to execute arbitrary code on a vulnerable system. VU#125776 - Multiple buffer overflows in Mozilla POP3 protocol handler There are multiple buffer overflow vulnerabilities in the Mozilla POP3 protocol handler that could allow a malicious POP3 server to execute arbitrary code on the affected system. VU#327560 - Mozilla "send page" feature contains a buffer overflow vulnerability There is a buffer overflow vulnerability in the Mozilla "send page" feature that could allow a remote attacker to execute arbitrary code. VU#651928 - Mozilla allows arbitrary code execution via link dragging A vulnerability affecting Mozilla web browsers may allow violation of cross-domain scripting policies and possibly execute code originating from a remote source. II. Impact These vulnerabilities could allow a remote attacker to execute arbitrary code with the privileges of the user running the affected application. VU#847200 could also allow a remote attacker to crash an affected application. III. Solution Upgrade to a patched version Mozilla has released versions of the affected software that contain patches for these issues: * Mozilla 1.7.3 * Firefox Preview Release * Thunderbird 0.8 Users are strongly encouraged to upgrade to one of these versions.
