Description OSIDB Bzimport 2026-10-19 14:36:48 UTC 
libaribcaption 1.1.0 through 1.1.2 contains a global out-of-bounds read in DecoderImpl::HandleGLGR() that reads past the 78-entry kLatinSpecialTable without an upper bound check. Attackers can supply crafted captions designating the Latin special set with ESC 28 4C followed by bytes 0x6F-0x7E to leak adjacent read-only data or crash decoding.
