Dylan Baker c0fa7879b2 libpkgconf: zero path lists after freeing
ci/woodpecker/push/woodpecker Pipeline was successful Details
This is required to make the pointer safely re-usable after being freed,
otherwise the list still says that it has nodes, but they point nowhere.
This is particularly important for libpkgconf, if a caller needs to
re-enter the library after freeing a path in a static path (such as the
default personality)

Ariadne Conill fd1b8ccca6 main: if PKG_CONFIG_FDO_SYSROOT_RULES is set, or DESTDIR matches PKG_CONFIG_SYSROOT_DIRS, disable the automatic sysroot rewriting
Closes #205.

Ariadne Conill 354c87279b libpkgconf: tuple: fix truncation when no overflow occurs 2020-05-30 19:20:25 -06:00
Tobias Stoeckmann 5eb9cae009 libpkgconf: tuple: fix out of boundary write
This is the same issue which has been fixed in dependency code.

If a line contains a variable which is longer than PKGCONF_ITEM_SIZE,
then the varname buffer overflows.

The code itself still does not check if a closing } exists and
truncates variable names which are too long. Since these would
be functional changes and this commit is about a protection against
undefined behaviour on a language level, these changes are not
included.

Proof of concept:
$ echo "Description: poc" > poc.pc
$ echo "Version: 1" >> poc.pc
$ echo -n 'Name: ${'
$ dd if=/dev/zero bs=1 count=66535 | tr '\0' 'x' >> poc.pc
$ echo >> poc.pc
$ pkgconf poc.pc

On my Linux system, when compiled with gcc, the varname buffer overflows
directly into buf, which means that no crash can be notified.

It's easiest to figure out when adding strlen() and sizeof() output
as debug lines.

tuple: Ensure buf length is always >= 1 in dequote
If a key is defined with no value, dequote will allocate a buffer with a
length of 0.  Since the buffer's length is 0, any manipulation of its
content is UB.

Example .pc file:

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

xcflags=
xlibs= -lSM -lICE  -lX11

Name: Obt
Description: Openbox Toolkit Library
Version: 3.6
Requires: glib-2.0 libxml-2.0
Libs: -L${libdir} -lobt ${xlibs}
Cflags: -I${includedir}/openbox/3.6 ${xcflags}

Output using pkgconf 1.5.2 on x86_64 Linux/musl:

% pkgconf --cflags obt-3.5
-I/usr/include/openbox/3.6 \�\\�I\�\ -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2

William Pitcock 9505213c1b tuple: check expanded variables to see if a sysroot has been duplicated, and if so, remove the prepended sysroot.
This allows compatibility between legacy pkg-config's broken sysroot implementation and pkgconf's sysroot
implementation, by removing any prepended sysroot paths and preferencing the variable expansion sysroot path
we typically do instead.

Closes github #123.
