An issue was discovered in musl libc 0.7.10 through 1.2.6. Stack-based memory corruption can occur during qsort of very large arrays, due to incorrectly implemented double-word primitives. The number of elements must exceed about seven million, i.e., the 32nd Leonardo number on 3...

HighCVSS 7.0 EPSS 0.35%
musl libc 0.9.13 through 1.2.5 before 1.2.6 has an out-of-bounds write vulnerability when an attacker can trigger iconv conversion of untrusted EUC-KR text to UTF-8.
-
MediumCVSS 5.5 EPSS 0.65%
In musl libc through 1.2.1, wcsnrtombs mishandles particular combinations of destination buffer size and source character limit, as demonstrated by an invalid write access (buffer overflow).
-
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...

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.
-
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.
-
CriticalCVSS 9.8 EPSS 2.2%
Stack-based buffer overflow in the inet_pton function in network/inet_pton.c in musl libc 0.9.15 through 1.0.4, and 1.1.0 through 1.1.7 allows attackers to have unspecified impact via unknown vectors.
