A flaw was found in libsolv, a dependency-resolution library used by RPM-based package managers such as dnf and zypper to work with.solv repository cache files. When libsolv rewrites a.solv cache file, it reads directory-id values from the file's compressed filelist data without validating that they fall within the expected range. A corrupted or specially crafted.solv cache file (for example, one left in a torn state after an unclean system shutdown) can cause an out-of-bounds memory write when a tool such as dnf, yum, or zypper next processes it.
