+OpenSSL Security Advisory [16th October 2024]
+=============================================
+
+Low-level invalid GF(2^m) parameters lead to OOB memory access (CVE-2024-9143)
+==============================================================================
+
+Severity: Low
+
+Issue summary: Use of the low-level GF(2^m) elliptic curve APIs with untrusted
+explicit values for the field polynomial can lead to out-of-bounds memory reads
+or writes.
+
+Impact summary: Out of bound memory writes can lead to an application crash or
+even a possibility of a remote code execution, however, in all the protocols
+involving Elliptic Curve Cryptography that we're aware of, either only "named
+curves" are supported, or, if explicit curve parameters are supported, they
+specify an X9.62 encoding of binary (GF(2^m)) curves that can't represent
+problematic input values. Thus the likelihood of existence of a vulnerable
+application is low.
+
+In particular, the X9.62 encoding is used for ECC keys in X.509 certificates,
+so problematic inputs cannot occur in the context of processing X.509
+certificates. Any problematic use-cases would have to be using an "exotic"
+curve encoding.
+
+The affected APIs include: EC_GROUP_new_curve_GF2m(), EC_GROUP_new_from_params(),
+and various supporting BN_GF2m_*() functions.
+
+Applications working with "exotic" explicit binary (GF(2^m)) curve parameters,
+that make it possible to represent invalid field polynomials with a zero
+constant term, via the above or similar APIs, may terminate abruptly as a
+result of reading or writing outside of array bounds. Remote code execution
+cannot easily be ruled out.
+
+The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
+
+OpenSSL 3.3, 3.2, 3.1, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue.
+
+OpenSSL 3.3 users should upgrade to OpenSSL 3.3.3 once it is released.
+
+OpenSSL 3.2 users should upgrade to OpenSSL 3.2.4 once it is released.
+
+OpenSSL 3.1 users should upgrade to OpenSSL 3.1.8 once it is released.
+
+OpenSSL 3.0 users should upgrade to OpenSSL 3.0.16 once it is released.
+
+OpenSSL 1.1.1 users should upgrade to OpenSSL 1.1.1zb once it is released
+(premium support customers only).
+
+OpenSSL 1.0.2 users should upgrade to OpenSSL 1.0.2zl once it is released
+(premium support customers only).
+
+Due to the low severity of this issue we are not issuing new releases of
+OpenSSL at this time. The fix will be included in the next release of each
+branch, once it becomes available. The fix is also available in commit
+c0d3e4d3 (for 3.3), commit bc7e04d7 (for 3.2), commit fdf67233 (for 3.1)
+and commit 72ae83ad (for 3.0) in the OpenSSL git repository. It is available
+to premium support customers in commit 8efc0cba (for 1.1.1) and in commit
+9d576994 (for 1.0.2).
+
+This issue was reported on 16th September 2024 by Google OSS-Fuzz-Gen.
+The fix was developed by Viktor Dukhovni.
