一、漏洞信息
漏洞编号：CVE-2024-21626
漏洞归属组件：buildah
漏洞归属的版本：1.26.1,1.34.1
CVSS V3.0分值：
BaseScore：8.6 High
Vector：CVSS：3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
漏洞简述：
runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace, allowing for a container escape by giving access to the host filesystem ( attack 2 ). The same attack could be used by a malicious image to allow a container process to gain access to the host filesystem through runc run ( attack 1 ). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries, allowing for complete container escapes ( attack 3a and attack 3b ). runc 1.1.12 includes patches for this issue.
