## Description

Imager versions before 1.036 for Perl exit the process reading a TGA with a
colour map length of 32768 or more in tga\_palette\_read.
The reader unpacks the two-byte colour map length into a signed short, so a
length of 32768 or more becomes negative. tga\_palette\_read() casts that
value to size\_t and asks mymalloc() for a size near SIZE\_MAX. The
allocation fails and Imager's allocator calls exit(3).
Reading an attacker-supplied file through Imager->read() triggers an
uncatchable exit.
