Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

An exploitable integer overflow vulnerability exists in the flattenIncrementally function in the xcf2png and xcf2pnm binaries of xcftools 1.0.7. An integer overflow can occur while calculating the row's allocation size, that could be exploited to corrupt memory and eventually execute arbitrary code. In order to trigger this vulnerability, a victim would need to open a specially crafted XCF file.
