    Debian Bug     : 432924
    Several local/remote vulnerabilities have been discovered in libarchive1,
    a single library to read/write tar, cpio, pax, zip, iso9660, archives.
    The Common Vulnerabilities and Exposures project identifies the following
      It was discovered that libarchive1 would miscompute the length of a buffer
      resulting in a buffer overflow if yet another type of corruption occurred
      in a pax extension header.
      It was discovered that if an archive prematurely ended within a pax
      extension header the libarchive1 library could enter an infinite loop.
      If an archive prematurely ended within a tar header, immediately following
      a pax extension header, libarchive1 could dereference a NULL pointer.
    The old stable distribution (sarge), does not contain this package.
    For the stable distribution (etch), these problems have been fixed in
    version 1.2.53-2etch1.
    For the unstable distribution (sid), these problems have been fixed in
    version 2.2.4-1.
    We recommend that you upgrade your libarchive package.
