Vulnerability CVE-2015-8983


Published: 2017-03-20   Modified: 2017-03-22

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.

Vendor: GNU
Product: Glibc 
Version: 2.21;
