Problem: The zipl boot loaders have their own minimalistic libc implementation. In it printf and sprintf use vsprintf for string formatting. Per definition vsprintf assumes that the buffer it writes to is large enough to contain the formatted string and performs no size checks. This is problematic for the boot loaders because the buffer they use are often allocated on the stack. Thus even small changes to the string format can potentially cause buffer overflows on the stack. Solution: Implement vsnprintf and make use of it. Reproduction: Use printf to print a string with >81 characters (exact number depends on the stack layout/compiler used).
