Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow.

remediations

Vendor fix, mitigation, or workaround guidance, as published by each source.

A vendor fix is available.

Fixedwago_psirt
Update your managed switch to the latest firmware: 852-303 (>= V1.2.2.S0) 852-1305 (>= V1.1.6.S0) 852-1505 (>= V1.1.5.S0) Firmwares published on Jun 7, 2019 or later are fixed. Please refer to the corresponding manual.
