A stack buffer overflow exists in the ec_glob function of editorconfig-core-c before v0.12.6 which allowed an attacker to arbitrarily write to the stack and possibly allows remote code execution. editorconfig-core-c v0.12.6 resolved this vulnerability by bound checking all write operations over the p_pcre buffer.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
