AZL-26918 CVE-2023-32067 affecting package fluent-bit for versions less than 2.1.10-1

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful...

AZL-26917 CVE-2023-31130 affecting package fluent-bit for versions less than 2.1.10-1

c-ares is an asynchronous resolver library. aresinetnetpton is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to...

AZL-26870 CVE-2023-31147 affecting package fluent-bit for versions less than 2.1.10-1

c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom are unavailable, c-ares uses rand to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand so will generate predictable output. Input from the random number generator i...

An issue was discovered in Treasure Data Fluent Bit 1.7.1 erroneous parsing in flb_pack_msgpack_to_json_format leads to type confusion bug that interprets whatever is on the stack as msgpack maps and arrays leading to use-after-free. This can be used by an attacker to craft a specially craft file and trick the victim opening it using the affect software triggering use-after-free and execute arbitrary code on the target system.
