Bug ID: 214237
Summary: Stack buffer lifetime mis-use in ncal(1)
Product: Base System
Version: 10.3-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: misc
Assignee: [email protected]
Reporter: [email protected]
The buffer used to obtain the standout start and standout end sequences from
termcap is used long after its lifetime has ended, and potentially something
else has written to that area of stack storage.
The fix is to adjust line 1113 of usr.bin/ncal/ncal.c to
static char cbuf[512];
char tbuf[1024], *b;
