There are multiple stack-based buffer overflow vulnerabilities in V-SFT (v6.2.2.0 and earlier), TELLUS (v4.0.19.0 and earlier), and TELLUS Lite (v4.0.19.0 and earlier). If a user opens a specially crafted file, information may be disclosed and/or arbitrary code may be executed.
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).
