Alpine: multiple redis packages: security update to 5.0.13-r0
high Tenable Cloud Security Plugin ID 406901
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Redis is an in-memory database that persists on disk. A vulnerability involving out-of-bounds read and
integer overflow to buffer overflow exists starting with version 2.2 and prior to versions 5.0.13, 6.0.15,
and 6.2.5. On 32-bit systems, Redis `*BIT*` command are vulnerable to integer overflow that can
potentially be exploited to corrupt the heap, leak arbitrary heap contents or trigger remote code
execution. The vulnerability involves changing the default `proto-max-bulk-len` configuration parameter to
a very large value and constructing specially crafted commands bit commands. This problem only affects
Redis on 32-bit platforms, or compiled as a 32-bit binary. Redis versions 5.0.`3m 6.0.15, and 6.2.5
contain patches for this issue. An additional workaround to mitigate the problem without patching the
`redis-server` executable is to prevent users from modifying the `proto-max-bulk-len` configuration
parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.
