USN-8895-1: Sudo vulnerability

It was discovered that Sudo did not properly handle time-based access restrictions when sudoers rules used NOTBEFORE or NOTAFTER with timestamps omitting the trailing timezone indicator. A local attacker could possibly use this issue to execute commands outside the intended time window by...

PHP openssl_x509_parse() Memory Corruption Vulnerability

The PHP function opensslx509parse uses a helper function called asn1timetotimet to convert timestamps from ASN1 string format into integer timestamp values. The parser within this helper function is not binary safe and can therefore be tricked to write up to five NUL bytes outside of an allocated...

php: memory corruption in openssl_x509_parse()

The asn1timetotimet function in ext/openssl/openssl.c in PHP before 5.3.28, 5.4.x before 5.4.23, and 5.5.x before 5.5.7 does not properly parse 1 notBefore and 2 notAfter timestamps in X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service memory...
