Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to computing a size in bytes, which triggers a heap-based buffer overflow.
