| Vector | AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
ImageMagick versions prior to 7.0.8-68
Description
The issue is related to a missing check for a 0 value of
replace extent in the SubstituteString() function, which can cause an offset p to overflow. This could be triggered by a crafted input file processed by ImageMagick, potentially impacting application availability. The flaw can be exploited by a remote attacker using a specially crafted file.Recommendations
For ImageMagick versions prior to 7.0.8-68, update to version 7.0.8-68 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted input files that could trigger the overflow in the SubstituteString() function.
