wv: Buffer overflow vulnerability Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200407-11 (wv: Buffer overflow vulnerability) A use of strcat without proper bounds checking leads to an exploitable buffer overflow. The vulnerable code is executed when wv encounters an unrecognized token, so a specially crafted file, loaded in wv, can trigger the vulnerable code and execute it's own arbitrary code. This exploit is only possible when the user loads the document into HTML view mode. Impact By inducing a user into running wv on a special file, a possible hacker can execute arbitrary code with the permissions of the user running the vulnerable program. Workaround Users should not view untrusted documents with wvHtml or applications using wv. When loading an untrusted document in an application using the wv library, make sure HTML view is disabled.
