CVE-2025-5917 PUBLISHED

Libarchive: off by one error in build_ustar_entry_name() at archive_write_set_format_pax.c

Assigner: redhat

A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one' miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to unpredictable program behavior, crashes, or in specific circumstances, could be leveraged as a building block for more sophisticated exploitation.
