Descriptions

A vulnerability has been identified in the libarchive library. This flaw can be triggered when file streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-bounds read can lead to unintended consequences, including unpredictable program behavior, memory corruption, or a denial-of-service condition.

Se ha identificado una vulnerabilidad en la librería libarchive. Esta falla puede activarse cuando se canalizan flujos de archivos a bsdtar, lo que podría permitir la lectura más allá del final del archivo. Esta lectura fuera de los límites puede tener consecuencias imprevistas, como un comportamiento impredecible del programa, corrupción de memoria o una condición de denegación de servicio.

This update for libarchive fixes the following issues. Fixed double free due to an integer overflow in the archive_read_format_rar_seek_data function. Fixed heap buffer over read in copy_from_lzss_window at archive_read_support_format_rar.c. Fixed integer overflow while reading warc files at archive_read_support_format_warc.c. Fixed off by one error in build_ustar_entry_name at archive_write_set_format_pax.c. Fixed reading past EOF may be triggered for piped file streams.
