Background ========== blktrace shows detailed information about what is happening on a block device IO queue. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-block/blktrace < 1.2.0_p20210419122502>= 1.2.0_p20210419122502 Description =========== A crafted file could cause a buffer overflow in the 'dev_map_read' function because the device and devno arrays are too small. Impact ====== A remote attacker could entice a user to open a specially crafted file using blktrace, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All blktrace users should upgrade to the latest version: # emerge --sync # emerge -a --oneshot -v ">=sys-block/blktrace-1.2.0_p20210419122502" References ========== [ 1 ] CVE-2018-10689 https://nvd.nist.gov/vuln/detail/CVE-2018-10689 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202107-15 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
