Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2021-0281)
Summary:	The remote host is missing an update for the 'bluez' package(s) announced via the MGASA-2021-0281 advisory.
Description:	Summary: The remote host is missing an update for the 'bluez' package(s) announced via the MGASA-2021-0281 advisory. Vulnerability Insight: Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time (CVE-2020-26558). The cli_feat_read_cb() function in src/gatt-database.c does not perform bounds checks on the 'offset' variable before using it as an index into an array for reading (CVE-2021-3588). Affected Software/OS: 'bluez' package(s) on Mageia 7, Mageia 8. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:A/AC:M/Au:N/C:P/I:P/A:N
