HIGH 7.8EPSS 0.20%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share v12 SP0 Build (1204.77), the affected applications lack proper validation of user-supplied data when parsing XE files. This could lead to an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
