Security Fix(es):
c-ares: A vulnerability was found in c-ares where the ares__read_line() 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 1.22.0, the /etc/hosts file. If the configuration files have an embedded NULL character as the first character in a new line, it can attempt to read memory before the start of the given buffer, which may result in a crash.(CVE-2024-25629)
c-ares: bugfix
tongsuo: A timing side-channel vulnerability was found in OpenSSL. This vulnerability allows an attacker to recover the private key. However, measuring the timing would require local access to the signing application or a fast network connection with low latency. There is a timing signal of around 300 nanoseconds when the top word of the inverted ECDSA nonce value is zero. This issue can happen with significant probability only for some of the supported elliptic curves. In particular, the NIST P-521 curve is affected.(CVE-2024-13176)
tongsuo: A flaw was found in OpenSSL. Use of the low-level GF(2^m) elliptic curve APIs with untrusted explicit values for the field polynomial can lead to out-of-bounds memory reads or writes. X9.62 encoding is used for ECC keys in X.509 certificates, so problematic inputs cannot occur in the context of processing X.509 certificates. Any problematic use-cases would have to be using an "exotic" curve encoding. Applications working with "exotic" explicit binary (GF(2^m)) curve parameters make it possible to represent invalid field polynomials with a zero constant term via the affected APIs (EC_GROUP_new_curve_GF2m(), EC_GROUP_new_from_params(), and various supporting BN_GF2m_*() functions) may terminate abruptly as a result of reading or writing outside of array bounds.(CVE-2024-9143)
