NVD Description

Note: Versions mentioned in the description apply only to the upstream wv package and not the wv package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

wvWare wv through 1.2.9 contains a stack-based out-of-bounds read vulnerability in wvGetPAPX_FKP and wvGetCHPX_FKP caused by an unvalidated FKP run count. Attackers can supply a crafted .doc file with a large crun value to read kilobytes past the 512-byte stack buffer, crashing applications like AbiWord.
