Description

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 (crash) via an invalid name length in a DNS response, related to an infinite loop with no output.

Affected

Musl · Musl Libc

95%

0.9.13 ≤ v ≤ 1.0.31.1.0 ≤ v < 1.1.2

Affected range stops below 1.1.2, so it looks safe — our inference, not a vendor statement

Libc Musl · Red Hat

60%

v ≤ 1.0.31.1x ≤ v < 1.1.2

Affected range stops below 1.1.2, so it looks safe — our inference, not a vendor statement
