AZL-59742 CVE-2025-31498 affecting package fluent-bit for versions less than 3.1.9-4

c-ares is an asynchronous resolver library. From 1.32.3 through 1.34.4, there is a use-after-free in readanswers when processanswer may re-enqueue a query either due to a DNS Cookie Failure or when the upstream server does not properly support EDNS, or possibly on TCP queries if the remote closed...

The vulnerability of the autotools CARES_RANDOM_FILE component in the C-ares asynchronous DNS query library allows a attacker to compromise the integrity of the protected information.

The vulnerability of the CARESRANDOMFILE component in the C-ares asynchronous DNS query library is related to the use of rand as a backup mechanism. This allows attackers to exploit the absence of entropy, without using CSPRNG. Exploiting this vulnerability enables remote attackers to compromise...

AZL-34687 CVE-2024-25629 affecting package fluent-bit for versions less than 3.0.6-1

c-ares is a C library for asynchronous DNS requests. aresreadline is used to parse local configuration files such as /etc/resolv.conf, /etc/nsswitch.conf, the HOSTALIASES file, and if using a c-ares version prior to 1.27.0, the /etc/hosts file. If any of these configuration files has an embedded...
