libzvbi through 0.2.45 contains an out-of-bounds write vulnerability in the Teletext decoder that allows attackers to corrupt memory by supplying unvalidated DRCS pixel-mode values in X/28/3 packets. Attackers can send a crafted Teletext stream decoded via vbi_decode with every slot set to DRCS_MODE_6_5_4, causing convert_drcs to overflow chars[48][60] and crash the application.
