Description OSIDB Bzimport 2026-10-18 12:42:18 UTC 
wvWare wv through 1.2.9 contains a heap-based out-of-bounds read vulnerability in wvGetSTSH in stylesheet.c that allows attackers to crash applications by supplying crafted Word stylesheets. Attackers can provide a .doc file with ten or fewer styles or out-of-range style base indexes to read past heap arrays, crashing applications such as AbiWord.
