Integer overflow in the _authenticate function in svc_auth.c in Wind River VxWorks 5.5 through 6.9.4.1, when the Remote Procedure Call (RPC) protocol is enabled, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a username and password.

Wind River VxWorks before 5.5.1, 6.5.x through 6.7.x before 6.7.1.1, 6.8.x before 6.8.3, 6.9.x before 6.9.4.4, and 7.x before 7 ipnet_coreip 1.2.2.0, as used on Schneider Electric SAGE RTU devices before J2 and other devices, does not properly generate TCP initial sequence number (ISN) values, which makes it easier for remote attackers to spoof TCP sessions by predicting an ISN value.

IPSSH (aka the SSH server) in Wind River VxWorks 6.5 through 6.9 allows remote authenticated users to cause a denial of service (daemon outage) via a crafted pty request.

IPSSH (aka the SSH server) in Wind River VxWorks 6.5 through 6.9 allows remote attackers to execute arbitrary code or cause a denial of service (daemon hang) via a crafted public-key authentication request.

The WebCLI component in Wind River VxWorks 5.5 through 6.9 allows remote authenticated users to cause a denial of service (CLI session crash) via a crafted command string.

The web server in Wind River VxWorks 5.5 through 6.9 allows remote attackers to cause a denial of service (daemon crash) via a crafted URI.

IPSSH (aka the SSH server) in Wind River VxWorks 6.5 through 6.9 allows remote attackers to cause a denial of service (daemon outage) via a crafted authentication request.

IPSSH (aka the SSH server) in Wind River VxWorks 6.5 through 6.9 allows remote authenticated users to cause a denial of service (daemon outage) via a crafted packet.

The INCLUDE_SECURITY functionality in Wind River VxWorks 6.x, 5.x, and earlier uses the LOGIN_USER_NAME and LOGIN_USER_PASSWORD (aka LOGIN_PASSWORD) parameters to create hardcoded credentials, which makes it easier for remote attackers to obtain access via a (1) telnet, (2) rlogin, or (3) FTP session.

The loginDefaultEncrypt algorithm in loginLib in Wind River VxWorks before 6.9 does not properly support a large set of distinct possible passwords, which makes it easier for remote attackers to obtain access via a (1) telnet, (2) rlogin, or (3) FTP session.

The FTP daemon in Wind River VxWorks does not close the TCP connection after a number of failed login attempts, which makes it easier for remote attackers to obtain access via a brute-force attack.

An issue was discovered in Wind River VxWorks 6.9 and 7. The function ``tarExtract`` implements TAR file extraction and thereby also processes files within an archive that have relative or absolute file paths. A developer using the "tarExtract" function may expect that the function will strip leading slashes from absolute paths or stop processing when encountering relative paths that are outside of the extraction path, unless otherwise forced. This could lead to unexpected and undocumented behavior, which in general could result in a directory traversal, and associated unexpected behavior.

In Wind River VxWorks 6.9 and 7, a specific crafted packet may lead to an out-of-bounds read during an IKE initial exchange scenario.

An issue was discovered in VxWorks 6.9 through 7. In the IKE component, a specifically crafted packet may lead to reading beyond the end of a buffer, or a double free.

An issue was discovered in Wind River VxWorks through 6.8. There is a possible stack overflow in dhcp server.

An issue was discovered in Wind River VxWorks before 6.5. There is a possible heap overflow in dhcp client.

An issue was discovered in Wind River VxWorks 7 before 21.03. A specially crafted packet may lead to buffer over-read on IKE.

An issue was discovered in Wind River VxWorks 7. The memory allocator has a possible integer overflow in calculating a memory block's size to be allocated by calloc(). As a result, the actual memory allocated is smaller than the buffer size specified by the arguments, leading to memory corruption.

integer overflow in calloc

In Wind River VxWorks, memory allocator has a possible overflow in calculating the memory block's size to be allocated by calloc(). As a result, the actual memory allocated is smaller than the buffer size specified by the arguments, leading to memory corruption.

httpRpmFs in WebCLI in Wind River VxWorks 5.5 through 7 SR0640 has no check for an escape from the web root.
