CVE-2017-16796
HighSummary
In SWFTools 0.9.2, the png_load function in lib/png.c does not check the return value of a realloc call, which allows remote attackers to cause a denial of service (invalid write and application crash) or possibly have unspecified other impact via vectors involving an IDAT tag in a crafted PNG file.
Risk Assessment
This vulnerability may lead to application crashes, disrupting service availability. There is also a risk of unspecified impact on the system if exploited by attackers.
Recommendation
It is recommended to update SWFTools to the latest version that includes security patches. Additionally, monitoring and analyzing PNG files uploaded to the system is advisable to detect potential attacks.
