Tobias Stoeckmann 9e16d2709c libpkgconf: personality: fix out of boundary access 
It is possible to set the instruction pointer to undefined values by
using an operator larger than ':' in ASCII.

Since the personality function array does not have 256 entries, an
invalid operator can overflow the array.

Proof of concept:

$ echo "a _ b" > poc
$ ln -s $(which pkgconf) poc-pkgconf
$ ./poc-pkgconf

Ben 011db1bb88 Do not complain about malformed whitespace from \n on Version line 
Every version line has a newline at the end; the malformed whitespace checker
should just check for trailing spaces and tabs.

Olaf Hering cdc2bf887e use correct autoconf macro name 
AC_CONFIG_MACRO_DIR without trailing S is known by autoconf since 2.58.
AC_CONFIG_MACRO_DIR with trailing S is known by autoconf newer than 2.69.

This fixes libtool after 'autoreconf -fi'.

Tobias Stoeckmann 92745ad9cb libpkgconf: parser: fix out of boundary access 
It is possible to trigger an out of boundary access with specially
crafted files. If a line consist of only a key and spaces, then
op will point to '\0'-ending of the buffer. Since p is iterated by
one byte right past this ending '\0', the next read access to p is
effectively out of bounds.

Theoretically this can also lead to out of boundary writes if spaces
are encountered.

Proof of concept (I recommend to compile with address sanitizer):

$ echo -n a > poc.pc
$ dd if=/dev/zero bs=1 count=65533 | tr '\0' ' ' >> poc.pc
$ pkgconf poc.pc

Tobias Stoeckmann bd4ed1ca02 libpkgconf: fileio: prevent buffer overflow. 
pkgconf_fgetline is called with a user-defined buffer, its size, and
a FILE stream to read input from.

If the buffer is almost completely filled and the file stream contains
an escaped character, then it is possible to trigger an off-by-one
buffer overflow with a '\0' character.

Easiest example to trigger this:

char buf[2];
pkgconf_fgetline(buf, sizeof(buf), stdin);

Enter "\\" (two backslashes) and press enter. If the library and the
program are compiled with address sanitizer, you will see the program
crashing. Otherwise it depends on your architecture what happens.

Since nobody should be using a buffer of only size 1 or 2, keep enough
space for a possibly escaped character in while loop by subtracting one
more byte for this situation, not just for '\0'.
