Mandriva Linux Security Advisory : libarchive (MDVSA-2013:147)
Medium Nessus Plugin ID 66157
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA vulnerability has been found and corrected in libarchive :
Fabian Yamaguchi reported a read buffer overflow flaw in libarchive on 64-bit systems where sizeof(size_t) is equal to 8. In the archive_write_zip_data() function in libarchive/ archive_write_set_format_zip.c, the 's' parameter is of type size_t (64 bit, unsigned) and is cast to a 64 bit signed integer. If 's' is larger than MAX_INT, it will not be set to 'zip->remaining_data_bytes' even though it is larger than 'zip->remaining_data_bytes', which leads to a buffer overflow when calling deflate(). This can lead to a segfault in an application that uses libarchive to create ZIP archives (CVE-2013-0211).
The updated packages have been patched to correct this issue.
SolutionUpdate the affected packages.
