  • CVE-2018-20103: Fixed an infinite recursion via crafted packet allows stack exhaustion and denial of service (bsc#1119419)

Other notable bug fixes:

  • Fix off-by-one write in dns_validate_dns_response()
  • Fix out-of-bounds read via signedness error in dns_validate_dns_response()
  • Prevent out-of-bounds read in dns_validate_dns_response()

Описание

An out-of-bounds read in dns_validate_dns_response in dns.c was discovered in HAProxy through 1.8.14. Due to a missing check when validating DNS responses, remote attackers might be able read the 16 bytes corresponding to an AAAA record from the non-initialized part of the buffer, possibly accessing anything that was left on the stack, or even past the end of the 8193-byte buffer, depending on the value of accepted_payload_size.

Описание

An issue was discovered in dns.c in HAProxy through 1.8.14. In the case of a compressed pointer, a crafted packet can trigger infinite recursion by making the pointer point to itself, or create a long chain of valid pointers resulting in stack exhaustion.
