CVE-2021-41991 (GCVE-0-2021-41991)
Vulnerability from nvd – Published: 2021-10-18 13:44 – Updated: 2024-08-04 03:22
VLAI
Summary
The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.
Severity
No CVSS data available.

CVE-2021-3449 (GCVE-0-2021-3449)
Vulnerability from nvd – Published: 2021-03-25 14:25 – Updated: 2024-09-17 03:43
VLAI
Title
NULL pointer deref in signature_algorithms processing
Summary
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).
Severity

CVE-2021-41991 (GCVE-0-2021-41991)
Vulnerability from cvelistv5 – Published: 2021-10-18 13:44 – Updated: 2024-08-04 03:22
VLAI
Summary
The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.
Severity
No CVSS data available.

CVE-2021-3449 (GCVE-0-2021-3449)
Vulnerability from cvelistv5 – Published: 2021-03-25 14:25 – Updated: 2024-09-17 03:43
VLAI
Title
NULL pointer deref in signature_algorithms processing
Summary
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).
Severity
No CVSS data available.
