CVE-2023-22652Public exploit

Application crash via out-of-bounds terminator write

Published Jun 1, 2023 · Updated May 13, 2025

Stack buffer overflow in openSUSE libeconf before 0.5.2 allows local users to crash applications via malformed configuration files. In lib/getfilecontents.c, read_file finds a comment character with strchr and writes a NUL byte at p+1 without verifying that p+1 remains inside the stack buffer. Exploitation requires a crafted file to be parsed by a consuming process; the grounded impact is an application crash, not code execution.
