IBM Lotus Notes 8.5.3.4

Integer overflow in IBM Notes 8.5.x before 8.5.3 FP4 Interim Fix 1 and 9.x before 9.0 Interim Fix 1 on Windows, and 8.5.x before 8.5.3 FP5 and 9.x before 9.0.1 on Linux, allows remote attackers to execute arbitrary code via a malformed PNG image in a previewed e-mail message, aka SPR NPEI96K82Q.

IBM Notes and Domino 8.5.x before 8.5.3 FP6 IF3 and 9.x before 9.0.1 FP1 on 32-bit Linux platforms use incorrect gcc options, which makes it easier for remote attackers to execute arbitrary code by leveraging the absence of the NX protection mechanism and placing crafted x86 code on the stack, aka SPR KLYH9GGS9W.
