Apple has plugged 17 security flaws in its Safari 8.0.4, Safari 7.1.4 and Safari 6.2.4 web browsers, which could be exploited by hackers.
Apple revealed the updates in a security advisory. The majority of the updates relate to issues in WebKit.
"Multiple memory corruption issues existed in WebKit. These issues were addressed through improved memory handling," explained the advisory.
"Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution."
The updates address 16 known threats listed in the Common Vulnerabilities and Exposures (CVE) system, one of which was reported by the Google Chrome Security Team.
The remaining fix patches a separate WebKit threat that could be exploited to target Safari users with phishing attacks.
"A user interface inconsistency existed in Safari that allowed an attacker to misrepresent the URL. This issue was addressed through improved user interface consistency checks," explained the advisory.
"[An] inconsistent user interface may prevent users from discerning a phishing attack."
Further details about the fixes, including if they were actively exploited by hackers, remain unknown.
Apple follows a stringent threat disclosure policy and offers little public information on security updates.
"For the protection of our customers, Apple does not disclose, discuss, or confirm security issues until a full investigation has occurred and any necessary patches or releases are available," reads the company policy.
The fixes come as a part of a wider set of security fixes by Apple. Apple released a number of patches plugging the Freak flaw earlier in March.
Freak is a cross-platform flaw in SSL/TLS protocols that could be exploited to intercept and decrypt HTTPS connections between vulnerable clients and servers.
Researchers at FireEye reported hundreds of "popular" iOS applications are still vulnerable to Freak, despite the update, on Wednesday.
