CVE-2017-14226
WP1StylesListener.cpp, WP5StylesListener.cpp, and WP42StylesListener.cpp in libwpd 0.10.1 mishandle iterators, which allows remote attackers to cause a denial of service (heap-based buffer over-read in the WPXTableList class in WPXTable.cpp).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.48%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
WP1StylesListener.cpp, WP5StylesListener.cpp, and WP42StylesListener.cpp in libwpd 0.10.1 mishandle iterators, which allows remote attackers to cause a denial of service (heap-based buffer over-read in the WPXTableList class in WPXTable.cpp). This vulnerability can be triggered in LibreOffice before 5.3.7. It may lead to suffering a remote attack against a LibreOffice application.
