GHSA-77QX-FFG2-4JRV

Vulnerability from github – Published: 2022-05-17 02:54 – Updated: 2025-04-20 03:34

Details

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.

Severity ?

8.1 (High)


                  
                    CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
