Apple » Macos : Security Vulnerabilities, CVEs, CVSS score between 5 and 5.99

A race condition was addressed with improved locking. This issue is fixed in Security Update 2021-004 Mojave, iOS 14.5 and iPadOS 14.5, watchOS 7.4, Security Update 2021-003 Catalina, tvOS 14.5, macOS Big Sur 11.3. A remote attacker may be able to cause a denial of service.

When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server.

The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i). Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x).

An attacker in a privileged network position may be able to misrepresent application state. This issue is fixed in macOS Big Sur 11.4, Security Update 2021-003 Catalina, Security Update 2021-004 Mojave. A logic issue was addressed with improved state management.

A logic issue was addressed with improved state management. This issue is fixed in macOS Big Sur 11.4, Security Update 2021-003 Catalina, Security Update 2021-004 Mojave. An attacker in a privileged network position may be able to perform denial of service.

An information disclosure issue was addressed with improved state management. This issue is fixed in macOS Big Sur 11.4, Security Update 2021-003 Catalina, Security Update 2021-004 Mojave. An attacker in a privileged network position may be able to leak sensitive user information.

A race condition was addressed with improved locking. This issue is fixed in macOS Monterey 12.1, Security Update 2021-008 Catalina, macOS Big Sur 11.6.2. A remote attacker may be able to cause unexpected application termination or heap corruption.

When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client.

An out-of-bounds read issue was addressed with improved bounds checking. This issue is fixed in Security Update 2022-005 Catalina, macOS Monterey 12.5. A user in a privileged network position may be able to leak sensitive information.

This issue was addressed with improved data protection. This issue is fixed in macOS Ventura 13. A user in a privileged network position may be able to track user activity.

A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path.

A race condition was addressed with additional validation. This issue is fixed in watchOS 9.3, tvOS 16.3, macOS Ventura 13.2, iOS 16.3 and iPadOS 16.3. A user may be able to read arbitrary files as root.

A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different backends for resolving host names, selected at build time. If it is built to use the synchronous resolver, it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this, libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore crash or otherwise misbehave.

An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`.

A timing side-channel issue was addressed with improvements to constant-time computation in cryptographic functions. This issue is fixed in macOS Sonoma 14.3, watchOS 10.3, tvOS 17.3, iOS 17.3 and iPadOS 17.3. An attacker may be able to decrypt legacy RSA PKCS#1 v1.5 ciphertexts without having the private key.

The issue was addressed with improved checks. This issue is fixed in macOS Sonoma 14.4, iOS 17.4 and iPadOS 17.4. An attacker in a privileged network position may be able to inject keystrokes by spoofing a keyboard.

A logic issue was addressed with improved restrictions. This issue is fixed in tvOS 14.6, iOS 14.6 and iPadOS 14.6, Safari 14.1.1, macOS Big Sur 11.4, watchOS 7.5. A malicious website may be able to access restricted ports on arbitrary servers.

A session rendering issue was addressed with improved session tracking. This issue is fixed in macOS Sonoma 14.2.1. A user who shares their screen may unintentionally share the incorrect content.

In FreeBSD 12.1-STABLE before r364644, 11.4-STABLE before r364651, 12.1-RELEASE before p9, 11.4-RELEASE before p3, and 11.3-RELEASE before p13, improper handling in the kernel causes a use-after-free bug by sending large user messages from multiple threads on the same SCTP socket. The use-after-free situation may result in unintended kernel behaviour including a kernel panic.

A logic issue was addressed with improved restrictions. This issue is fixed in macOS Big Sur 11.0.1. A malicious application with root privileges may be able to access private information.

SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.

SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c.

In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.

The issue was addressed with additional user controls. This issue is fixed in macOS Big Sur 11.0.1. Users may be unable to remove metadata indicating where files were downloaded from.

A path handling issue was addressed with improved validation. This issue is fixed in macOS Big Sur 11.0.1. A remote attacker may be able to modify the file system.
