NULL Pointer Dereference

  • Vulnerable module: openssl/libcrypto1.1
  • Introduced through: openssl/libcrypto1.1@1.1.1d-r2 and openssl/libssl1.1@1.1.1d-r2
  • Fixed in: 1.1.1g-r0

Detailed paths

  • Introduced through: fluent/fluentd:v1.10.2-1.0@* openssl/libcrypto1.1@1.1.1d-r2
  • Introduced through: fluent/fluentd:v1.10.2-1.0@* openssl/libssl1.1@1.1.1d-r2

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference. Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).

Remediation

Upgrade openssl to version or higher.

Out-of-bounds Write

  • Vulnerable module: musl/musl
  • Introduced through: musl/musl@1.1.20-r5 and musl/musl-utils@1.1.20-r5
  • Fixed in: 1.1.20-r6

Detailed paths

  • Introduced through: fluent/fluentd:v1.10.2-1.0@* musl/musl@1.1.20-r5
  • Introduced through: fluent/fluentd:v1.10.2-1.0@* musl/musl-utils@1.1.20-r5

Overview

Affected versions of this package are vulnerable to Out-of-bounds Write. 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).

Remediation

Upgrade musl to version or higher.
