Описание
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228.
A flaw was found in glibc. If an attacker provides the iconv function with invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, IBM1399 encodings, it fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service.
Отчет
Red Hat Product Security has rated this flaw as a "Low" severity rating because the affected encodings are uncommon, and an attacker would need to either have local privileges or depend on an application feeding untrusted encoding input to iconv. Low and Moderate severity flaws are out of support scope for glibc as shipped with:
- Red Hat Enterprise Linux 5
- Red Hat Enterprise Linux 6
- Red Hat Enterprise Linux 7 For more detailed information about Red Hat Enterprise Linux support phases, please see [1].
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
