Summary
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.
Security Fix(es):
* openssl: Unbounded memory growth with session handling in TLSv1.3 (CVE-2024-2511)
* openssl: Excessive time spent checking DSA keys and parameters (CVE-2024-4603)
* openssl: Use After Free with SSL_free_buffers (CVE-2024-4741)
* openssl: SSL_select_next_proto buffer overread (CVE-2024-5535)

Vulnerabilities 4
-
Critical 9.8
Use After Free with SSL_free_buffers
Issue summary: Calling the OpenSSL API function SSL_free_buffers may cause memory to be accessed that was previously freed in some situations Impact summary: A use after free can have a range of potential consequences such as the corruption of valid data, cra…
-
Critical 9.1CVE-2024-5535 Public exploit
SSL_select_next_proto buffer overread
Issue summary: Calling the OpenSSL API function SSL_select_next_proto with an empty supported client protocols buffer may cause a crash or memory contents to be sent to the peer. Impact summary: A buffer overread can have a range of potential consequences suc…

Medium 5.9CVE-2024-2511 EPSS 59%
Unbounded memory growth with session handling in TLSv1.3
Issue summary: Some non-default TLS server configurations can cause unbounded memory growth when processing TLSv1.3 sessions Impact summary: An attacker may exploit certain server configurations to trigger unbounded memory growth that would lead to a Denial o…
-
Medium 5.3
Excessive time spent checking DSA keys and parameters
Issue summary: Checking excessively long DSA keys or parameters may be very slow. Impact summary: Applications that use the functions EVP_PKEY_param_check() or EVP_PKEY_public_check() to check a DSA public key or DSA parameters may experience long delays. Whe…
