CVE-2007-2052 is a vulnerability of currently unknown severity. Off-by-one error in the PyLocale_strxfrm function in Modules/_localemodule.c for Python 2.4 and 2.5 causes an incorrect buffer size to be used for the strxfrm function, which allows context-dependent attackers to read portions of memory via unknown manipulations that trigger a buffer over-read due to missing null termination.. EPSS estimates a 12.48% chance of exploitation in the next 30 days.
