Mozilla String Library Memory Overwrite Vulnerability

oval:org.mitre.oval:def:100040

String handling functions in Mozilla 1.7.3 Firefox 1.0 and Thunderbird before 1.0.2 such as the nsTSubstring_CharT::Replace function do not properly check the return values of other functions that resize the string which allows remote attackers to cause a denial of service and possibly execute arbitrary code by forcing an out-of-memory state that causes a reallocation to fail and return a pointer to a fixed address which leads to heap corruption.
