Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Magick.NET-Q16 packages before 14.10.4 have a stack buffer overflow in the MNG encoder, caused by missing bounds checks that let attacker-controlled data corrupt the stack. The source gives few details on how it is triggered or what access an attacker needs. Upgrade the affected packages to 14.10.4.
