libid3tag: Denial of service

Background

libid3tag is an ID3 tag manipulation library.

Description

Kentaro Oda reported an infinite loop in the file field.c when parsing an MP3 file with an ID3_FIELD_TYPE_STRINGLIST field that ends in ‘\0’.

Impact

A remote attacker could entice a user to open a specially crafted MP3 file, possibly resulting in a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All libid3tag users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/libid3tag-0.15.1b-r2"
