        "Description": "This update upgrades nbd to version 3.25-alt1. \nSecurity Fix(es):\n\n * BDU:2022-01639: Уязвимость реализации сетевых блочных устройств nbd, связанная с целочисленным переполнением, позволяющая нарушителю выполнить произвольный код\n\n * BDU:2022-01643: Уязвимость реализации сетевых блочных устройств nbd, связанная с переполнением буфера в стека, позволяющая нарушителю выполнить произвольный код\n\n * CVE-2022-26495: In nbd-server in nbd before 3.24, there is 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. This issue exists for the NBD_OPT_INFO, NBD_OPT_GO, and NBD_OPT_EXPORT_NAME messages.\n\n * CVE-2022-26496: In nbd-server in nbd before 3.24, there is a 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.",
