Microsoft Excel 2002 SP3 and 2003 SP3, Office 2004 and 2008 for Mac, and Open XML File Format Converter for Mac allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted HLink record in an Excel file, aka "Excel Buffer Overwrite Vulnerability."

Detection & IOCsextracted from sources · hover to see the quote
- →Trigger is a crafted HLink record embedded within an Excel file (.xls); inspect Excel files for malformed or oversized HLink records as an indicator of exploit attempts. ↗
- →Attack vector is social engineering to open a specially crafted Excel file; monitor for Excel process spawning unexpected child processes after opening untrusted .xls files. ↗
- →Exploitation targets Microsoft Excel 2002 SP3 and 2003 SP3; flag execution of these specific Excel versions opening externally sourced .xls files. ↗
- ·Affected platforms include both Windows (Excel 2002 SP3, 2003 SP3) and Mac (Office 2004, 2008, Open XML File Format Converter); detection rules should account for both platform contexts. ↗
- ·Failed exploit attempts manifest as a denial-of-service (crash) rather than code execution; memory corruption crashes of Excel.exe may indicate attempted exploitation even without successful payload delivery. ↗

CVE-2014-0104 fence-agents: no verification of remote SSL certificates

CVE-2014-0104 [MEDIUM] CVE-2014-0104 fence-agents: no verification of remote SSL certificates
CVE-2014-0104 fence-agents: no verification of remote SSL certificates
Michael Samuel reported that fence-agents does not verify remote SSL certificates in the fence_cisco_ucs.py script. This could potentially allow for man-in-the-middle attackers to spoof SSL servers via arbitrary, yet valid, SSL certificates.
This script did verify the validity of SSL certificates by default, but this behaviour was changed due to bug #691392, which introduced this behaviour via RHBA-2011:0834 [1].
* The fence_cisco_ucs script no longer checks the validity of SSL certificates by default. (BZ#691392)
Also note that this behaviour appears in the fence_rhevm.py script as well.
