Description Agostino Sarubbo gentoo-dev 2013-03-28 16:54:57 UTC
From ${URL} :

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.

3.1.2-r1 in Portage with the upstream patch for this issue:

Please test and mark it stable. Thank you!

Added to existing GLSA request.

CVE-2013-0211 (
  Integer signedness error in the archive_write_zip_data function in
  archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running
  on 64-bit machines, allows context-dependent attackers to cause a denial of
  service (crash) via unspecified vectors, which triggers an improper
  conversion between unsigned and signed types, leading to a buffer overflow.

This issue was resolved and addressed in
 GLSA 201406-02 at
