In pkgconf through 1.9.3, variable duplication can cause unbounded string expansion due to incorrect checks in libpkgconf/tuple.c:pkgconf_tuple_parse. For example, a .pc file containing a few hundred bytes can expand to one billion bytes.
A flaw was found in pkgconf, where a variable duplication can cause unbounded string expansion due to incorrect checks in libpkgconf/tuple.c:pkgconf_tuple_parse. This issue may lead to a buffer overflow, which can crash the software.
Отчет
pkgconf is a program which helps to configure compiler and linker flags for development libraries, & this security flaw can only crash while compiling/building a package in a development environment, hence that provides a very minimal Impact. Also Red Hat Enterprise Linux 8 and 9 provide the stack protector in gcc, FORTIFY_SOURCE in glibc to protect against heap based overflows.
