Apple » Mac Os X : Security Vulnerabilities, CVEs, (Denial of service)

OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, does not properly handle ASCII representations of integers on 64 bit platforms, which could allow attackers to cause a denial of service and possibly execute arbitrary code.

The ASN1 library in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allows remote attackers to cause a denial of service via invalid encodings.

IPSEC implementations including (1) FreeS/WAN and (2) KAME do not properly calculate the length of authentication data, which allows remote attackers to cause a denial of service (kernel panic) via spoofed, short Encapsulating Security Payload (ESP) packets, which result in integer signedness errors.

The Sun RPC functionality in multiple libc implementations does not provide a time-out mechanism when reading data from TCP connections, which allows remote attackers to cause a denial of service (hang).

Mac OS X 10.2.2 allows remote attackers to cause a denial of service by accessing the CUPS Printing Web Administration utility, aka "CUPS Printing Web Administration is Remotely Accessible."

Multiple buffer overflows in Cyrus SASL library 2.1.9 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) long inputs during user name canonicalization, (2) characters that need to be escaped during LDAP authentication using saslauthd, or (3) an off-by-one error in the log writer, which does not allocate space for the null character that terminates a string.

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by causing negative arguments to be fed into memcpy() calls via HTTP requests with (1) a negative Content-Length value or (2) a negative length in a chunked transfer encoding.

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly check the return values of various file and socket operations, which could allow a remote attacker to cause a denial of service (resource exhaustion) by causing file descriptors to be assigned and not released, as demonstrated by fanta.

The arplookup function in FreeBSD 5.1 and earlier, Mac OS X before 10.2.8, and possibly other BSD-based systems, allows remote attackers on a local subnet to cause a denial of service (resource starvation and panic) via a flood of spoofed ARP requests.

Buffer overflow in the Mac OS X kernel 10.2.8 and earlier allows local users, and possibly remote attackers, to cause a denial of service (crash), access portions of memory, and possibly execute arbitrary code via a long command line argument (argv[]).

The PKI functionality in Mac OS X 10.2.8 and 10.3.2 allows remote attackers to cause a denial of service (service crash) via malformed ASN.1 sequences.

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.

The TCP/IP Networking component in Mac OS X before 10.3.5 allows remote attackers to cause a denial of service (memory and resource consumption) via a "Rose Attack" that involves sending a subset of small IP fragments that do not form a complete, larger packet.

Multiple integer overflows in libtiff 3.6.1 and earlier allow remote attackers to cause a denial of service (crash or memory corruption) via TIFF images that lead to incorrect malloc calls.

Darwin Streaming Server 5.0.1, and possibly earlier versions, allows remote attackers to cause a denial of service (server crash) via a DESCRIBE request with a location that contains a null byte.

Heap-based buffer overflow in the syscall emulation functionality in Mac OS X before 10.3.9 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code via crafted parameters.

Unknown vulnerability in the setsockopt system call in Mac OS X 10.3.9 and earlier allows local users to cause a denial of service (memory exhaustion) via crafted arguments.

Integer signedness error in the parse_machfile function in the mach-o loader (mach_loader.c) for the Darwin Kernel as used in Mac OS X 10.3.7, and other versions before 10.3.9, allows local users to cause a denial of service (CPU consumption) via a crafted mach-o header.

exif.c in PHP before 4.3.11 allows remote attackers to cause a denial of service (memory consumption and crash) via an EXIF header with a large IFD nesting level, which causes significant stack recursion.

bzip2 allows remote attackers to cause a denial of service (hard drive consumption) via a crafted bzip2 file that causes an infinite loop (a.k.a "decompression bomb").

AppKit in Mac OS X 10.3.9 allows attackers to cause a denial of service (Cocoa application crash) via a malformed TIFF image that causes the NXSeek to use an incorrect offset, leading to an unhandled exception.

Unspecified vulnerability in the Apple Mac OS X kernel before 10.4.2 allows remote attackers to cause a denial of service (kernel panic) via a crafted TCP packet, possibly related to source routing or loose source routing.

Algorithmic complexity vulnerability in CoreFoundation in Mac OS X 10.3.9 and 10.4.2 allows attackers to cause a denial of service (CPU consumption) via crafted Gregorian dates.
