Multiple vulnerabilities in Amarok might allow for user-assisted execution of arbitrary code.

2.  Impact Information


Amarok is an advanced music player.


Tobias Klein has discovered multiple vulnerabilities in Amarok:

  • Multiple integer overflows in the Audible::Tag::readTag() function in metadata/audible/audibletag.cpp trigger heap-based buffer overflows (CVE-2009-0135).
  • Multiple array index errors in the Audible::Tag::readTag() function in metadata/audible/audibletag.cpp can lead to invalid pointer dereferences, or the writing of a 0x00 byte to an arbitrary memory location after an allocation failure (CVE-2009-0136).


A remote attacker could entice a user to open a specially crafted Audible Audio (.aa) file with a large "nlen" or "vlen" tag value to execute arbitrary code or cause a Denial of Service.

3.  Resolution Information


There is no known workaround at this time.


All Amarok users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/amarok-1.4.10-r2"
