CVE-2008-1887 is a vulnerability of currently unknown severity. Python 2.5.2 and earlier allows context-dependent attackers to execute arbitrary code via multiple vectors that cause a negative size value to be provided to the PyString_FromStringAndSize function, which allocates less memory than expected when assert() is disabled and triggers a buffer overflow.. EPSS estimates a 6.29% chance of exploitation in the next 30 days.
