Fixed validation of embedded certificates was when checking OCSP responses CVE-2022-43705...

MGASA-2017-0422 Updated botan packages fix security vulnerability

In the Montgomery exponentiation code, a table of precomputed values is used. An attacker able to analyze which cache lines were accessed perhaps via an active attack such as Prime+Probe could recover information about the exponent CVE-2017-14737...

MGASA-2017-0327 Updated botan packages fix security vulnerability

Aleksandar Nikolic discovered that an error in the x509 parser of the Botan crypto library could result in an out-of-bounds memory read, resulting in denial of service or an information leak if processing a malformed certificate CVE-2017-2801...

MGASA-2017-0321 Updated botan packages fix security vulnerabilities

While decoding BER length fields, an integer overflow could occur. This could occur while parsing untrusted inputs such as X.509 certificates. The overflow does not seem to lead to any obviously exploitable condition, but exploitation cannot be positively ruled out. Only 32-bit platforms are like...

MGASA-2016-0208 Updated botan packages fix security vulnerabilities

Updated botan packages fix security vulnerabilities: During RSA decryption, how long decoding of PKCS 1 v1.5 padding took was input dependent. If these differences could be measured by an attacker, it could be used to mount a Bleichenbacher million-message attack CVE-2015-7827. ECDSA and DSA...
