5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:N/A:P

Description

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.

Affected configurations

• mozilla firefox 1.0 • mozilla mozilla 1.7.3 • mozilla thunderbird 0.1 • mozilla thunderbird 0.2 • mozilla thunderbird 0.3 • mozilla thunderbird 0.4 • mozilla thunderbird 0.5 • mozilla thunderbird 0.6 • mozilla thunderbird 0.7 • mozilla thunderbird 0.8 • mozilla thunderbird 0.9 • mozilla thunderbird 1.0
