The remote host is affected by the vulnerability described in GLSA-200501-20 (o3read: Buffer overflow during file conversion)
Wiktor Kopec discovered that the parse_html function in o3read.c copies any number of bytes into a 1024-byte t[] array.
Impact :
Using a specially crafted file, possibly delivered by e-mail or over the Web, an attacker may execute arbitrary code with the permissions of the user running o3read.
Workaround :
There is no known workaround at this time.
