  1. CriticalCVSS 9.8 EPSS 2.2%

    Multiple stack-based buffer overflows in the __dn_expand function in network/dn_expand.c in musl libc 1.1x before 1.1.2 and 0.9.13 through 1.0.3 allow remote attackers to (1) have unspecified impact via an invalid name length in a DNS response or (2) cause a denial of service (cr...

  2. CriticalCVSS 9.8 EPSS 2.5%

    musl libc through 1.1.23 has an x87 floating-point stack adjustment imbalance, related to the math/i386/ directory. In some cases, use of this library could introduce out-of-bounds writes that are not present in an application's source code.

  3. HighCVSS 7.5 EPSS 2.0%

    musl libc before 1.1.17 has a buffer overflow via crafted DNS replies because dns_parse_callback in network/lookup_name.c does not restrict the number of addresses, and thus an attacker can provide an unexpected number by sending A records in a reply to an AAAA query.
