Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2022-0403)
Summary:	The remote host is missing an update for the 'nbd' package(s) announced via the MGASA-2022-0403 advisory.
Description:	Summary: The remote host is missing an update for the 'nbd' package(s) announced via the MGASA-2022-0403 advisory. Vulnerability Insight: It was discovered that nbd prior to 3.24 contained an integer overflow with a resultant heap-based buffer overflow. A value of 0xffffffff in the name length field will cause a zero-sized buffer to be allocated for the name resulting in a write to a dangling pointer (CVE-2022-26495). Stack-based buffer overflow. An attacker can cause a buffer overflow in the parsing of the name field by sending a crafted NBD_OPT_INFO or NBD_OPT_GO message with an large value as the length of the name. (CVE-2022-26496) Packaging has been adjusted to create the required nbd user and group at installation. Affected Software/OS: 'nbd' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
