RedHat: RHSA-2022-7700:01 Moderate: gdisk security update
Summary
The gdisk packages provide the gdisk partitioning utility for GUID
Partition Table (GPT) disks. The utility features a command-line interface
similar to fdisk, direct manipulation of partition table structures,
recovery tools to deal with corrupt partition tables, and the ability to
convert Master Boot Record (MBR) disks to the GPT format.
Security Fix(es):
* gdisk: possible out-of-bounds-write in LoadPartitionTable of gpt.cc
(CVE-2020-0256)
* gdisk: possible out-of-bounds-write in ReadLogicalParts of basicmbr.cc
(CVE-2021-0308)
