Description

The remote host is affected by the vulnerability described in GLSA-200810-01 (WordNet: Execution of arbitrary code)

Jukka Ruohonen initially reported a boundary error within the
searchwn() function in src/wn.c. A thorough investigation by the oCERT
team revealed several other vulnerabilities in WordNet:
Jukka Ruohonen and Rob Holland (oCERT) reported multiple boundary
errors within the searchwn() function in src/wn.c, the wngrep()
function in lib/search.c, the morphstr() and morphword() functions in
lib/morph.c, and the getindex() in lib/search.c, which lead to
stack-based buffer overflows.
Rob Holland (oCERT) reported two
boundary errors within the do_init() function in lib/morph.c, which
lead to stack-based buffer overflows via specially crafted
'WNSEARCHDIR' or 'WNHOME' environment variables.
Rob Holland
(oCERT) reported multiple boundary errors in the bin_search() and
bin_search_key() functions in binsrch.c, which lead to stack-based
buffer overflows via specially crafted data files.
Rob Holland
(oCERT) reported a boundary error within the parse_index() function in
lib/search.c, which leads to a heap-based buffer overflow via specially
crafted data files.

Impact :

In case the application is accessible e.g. via a web server,
a remote attacker could pass overly long strings as arguments to the
'wm' binary, possibly leading to the execution of arbitrary code.
A local attacker could exploit the second vulnerability via
specially crafted 'WNSEARCHDIR' or 'WNHOME' environment variables,
possibly leading to the execution of arbitrary code with escalated
privileges.
A local attacker could exploit the third and
fourth vulnerability by making the application use specially crafted
data files, possibly leading to the execution of arbitrary code.

Workaround :

There is no known workaround at this time.
