CVE Descriptions

The gfxTextRun::SanitizeGlyphRuns function in gfx/thebes/src/gfxFont.cpp in the browser engine in Mozilla Firefox 3.6 before 3.6.2 on Mac OS X, when the Core Text API is used, does not properly perform certain deletions, which allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via an HTML document containing invisible Unicode characters, as demonstrated by the U+FEFF, U+FFF9, U+FFFA, and U+FFFB characters.

Related Weaknesses

CWE-ID Weakness Name Source
CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/38943/info Mozilla Firefox is prone to a remote memory-corruption vulnerability. Successful exploits may allow an attacker to execute arbitrary code in the context of the user running the affected application. Failed exploit attempts will result in a denial-of-service condition. Firefox 3.6 for Apple Mac OS X is vulnerable. NOTE: This issue was previously covered in BID 38918 (Mozilla Firefox Thunderbird and Seamonkey MFSA 2010-09 through -15 Multiple Vulnerabilities) but has been assigned its own record to better document it. <html> <head> <title>Testcase for bug 538065</title> <style type="text/css"> span.test { background: #ff0; } </style> </head> <body> <p>U+FEFF: <span class="test">&#xfeff;</span></p> <p>U+FFF9: <span class="test">&#xfff9;</span></p> <p>U+FFFA: <span class="test">&#xfffa;</span></p> <p>U+FFFB: <span class="test">&#xfffb;</span></p> </body> </html>
