Background ========== WordNet is a large lexical database of English. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-dicts/wordnet < 3.0-r2 >=3D 3.0-r2 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 ">=3Dapp-dicts/wordnet-3.0-r2" References ========== [ 1 ] CVE-2008-2149 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2008-2149 [ 2 ] CVE-2008-3908 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2008-3908 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200810-01.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
