CVE-2014-8145 sox: two heap out-of-bounds access issues (oCERT-2014-010)
Last modified: 2015-06-03 04:57:16 EDT
oCERT reports sox vulnerabilities found by Michele Spagnuolo of Google Security Team: """ We have 2 heap-oob (one sometimes also causes SIGSEGV), 1 null pointer dereference and 6 divisions by zero that reproduce in both 14.3.1 and 14.4.1. The memory corruptions on the heap are potentially exploitable. The divisions by zero and the *(0x0), of course, are not security relevant. The maintainer provided 2 patches (they are attached) which have been validated by original report. """ Acknowledgement: Red Hat would like to thank oCERT for reporting these issues. oCERT acknowledges Michele Spagnuolo of the Google Security Team as the original reporter.
