Detail

Synopsis

Multiple vulnerabilities were found in WordNet, possibly allowing for the execution of arbitrary code.

Background

WordNet is a large lexical database of English.

Description

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.

Resolution

All WordNet users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-dicts/wordnet-3.0-r2"

Id Description
48479 Princeton WordNet (wn) morph.c Command Line Local Overflow

A local overflow exists in WordNet. WordNet fails to handle a boundary error in morph.c resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.
48478 Princeton WordNet (wn) search.c Multiple Local Overflows

A local overflow exists in WordNet. WordNet fails to handle multiple boundary errors in search.c resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.
48477 Princeton WordNet (wn) morph.c Environment Variable Handling Local Overflow

A local overflow exists in WordNet. WordNet fails to handle boundary errors within the "do_init()" function in lib/morph.c accessible via specially crafted "WNSEARCHDIR" or "WNHOME" environment variables resulting in a stack-based buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.
48476 Princeton WordNet (wn) wnutil.c Environment Variable Handling Local Overflow

A buffer overflow exists in WordNet. WordNet fails to handle a boundary in wnulitc. specifically called via the WNDBVERSION environmental variable resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.
48475 Princeton WordNet (wn) binsrch.c Data File Handling Local Overflow

A local overflow exists in WordNet. WordNet experiences boundary errors in "bin_search()" and "bin_search_key()" functions in binsrch.c resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code executio resulting in a loss of integrity.
