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.

Untrusted search path vulnerability in eSignal 10.6.2425.1208, and possibly other versions, allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse JRS_UT.dll that is located in the same folder as a .quo (QUOTE) file. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
