Vulnerability Details : CVE-2011-3494

WinSig.exe in eSignal 10.6.2425 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) a long StyleTemplate element in a QUO, SUM or POR file, which triggers a stack-based buffer overflow, or (2) a long Font->FaceName field (aka FaceName element), which triggers a heap-based buffer overflow. NOTE: some of these details are obtained from third party information.

- Metasploit Modules Related To CVE-2011-3494

eSignal and eSignal Pro File Parsing Buffer Overflow in QUO
The software is unable to handle the "<StyleTemplate>" files (even those original included in the program) like those with the registered extensions QUO, SUM and POR. Successful exploitation of this vulnerability may take up to several seconds due to the use of egghunter. Also, DEP bypass is unlikely due to the limited space for payload. This vulnerability affects versions 10.6.2425.1208 and earlier.
