libaribcaption DecoderImpl::HandleGLGR Out-of-Bounds Read Vulnerability

Sources read

Source agreement

0/2

Evidence confidence

%39

Short explanation

libaribcaption versions 1.1.0 through 1.1.2 contain a global out-of-bounds read vulnerability in DecoderImpl::HandleGLGR(). This flaw occurs because data is read past the 78-entry kLatinSpecialTable without an upper bound check.

Why does it matter?

Attackers can supply crafted captions to leak adjacent read-only data or cause decoding crashes.

What should be done?

Follow the vendor advisory or provided patch reference
Update the libaribcaption library
