+Subject: [PATCH] src/common.c: Fix heap buffer overflows when writing strings
+ in binheader
+
+Fixes the following problems:
+ 1. Case 's' only enlarges the buffer by 16 bytes instead of size bytes.
+ 2. psf_binheader_writef() enlarges the header buffer (if needed) prior to the
+ big switch statement by an amount (16 bytes) which is enough for all cases
+ where only a single value gets added. Cases 's', 'S', 'p' however
+ additionally write an arbitrary length block of data and again enlarge the
+ buffer to the required amount. However, the required space calculation does
+ not take into account the size of the length field which gets output before
+ the data.
+ 3. Buffer size requirement calculation in case 'S' does not account for the
+ padding byte ("size += (size & 1) ;" happens after the calculation which
+ uses "size").
+ 4. Case 'S' can overrun the header buffer by 1 byte when no padding is
+ involved
+ ("memcpy (&(psf->header.ptr [psf->header.indx]), strptr, size + 1) ;" while
+ the buffer is only guaranteed to have "size" space available).
+ 5. "psf->header.ptr [psf->header.indx] = 0 ;" in case 'S' always writes 1 byte
+ beyond the space which is guaranteed to be allocated in the header buffer.
+ 6. Case 's' can overrun the provided source string by 1 byte if padding is
+ involved ("memcpy (&(psf->header.ptr [psf->header.indx]), strptr, size) ;"
+ where "size" is "strlen (strptr) + 1" (which includes the 0 terminator,
+ plus optionally another 1 which is padding and not guaranteed to be
+ readable via the source string pointer).
