Description Andrej Nemec 2017-03-17 09:57:01 UTC 
An issue was discovered in CHICKEN Scheme through. When using a nonstandard CHICKEN-specific extension to allocate an SRFI-4 vector in unmanaged memory, the vector size would be used in unsanitised form as an argument to malloc(). With an unexpected size, the impact may have been a segfault or buffer overflow.
