Multiple buffer overflow vulnerabilities in REST API in Brocade Fabric OS versions v8.2.1 through v8.2.1d, and 8.2.2 versions before v8.2.2c could allow remote unauthenticated attackers to perform various attacks.

A vulnerability in the command-line interface in Brocade Fabric OS before Brocade Fabric OS v8.2.2a1, 8.2.2c, v7.4.2g, v8.2.0_CBN3, v8.2.1e, v8.1.2k, v9.0.0, could allow a local authenticated attacker to modify shell variables, which may lead to an escalation of privileges or bypassing the logging.

Brocade Fabric OS versions before Brocade Fabric OS v9.0.0, v8.2.2c, v8.2.1e, v8.1.2k, v8.2.0_CBN3, contains code injection and privilege escalation vulnerability.

Brocade Fabric OS versions before Brocade Fabric OS v7.4.2g could allow an authenticated, remote attacker to view a user password in cleartext. The vulnerability is due to incorrectly logging the user password in log files.

Supportlink CLI in Brocade Fabric OS Versions v8.2.1 through v8.2.1d, and 8.2.2 versions before v8.2.2c does not obfuscate the password field, which could expose users’ credentials of the remote server. An authenticated user could obtain the exposed password credentials to gain access to the remote host.

glib-networking: GTlsClientConnection silently ignores unset server identity

In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification. Applications that fail to provide the server identity, including Balsa before 2.5.11 and 2.6.x before 2.6.1, accept a TLS certificate if the certificate is valid for any host.

kernel: A memory leak in the fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c allows for a DoS

A memory leak in the fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering dma_get_sgtable() failures, aka CID-fc739a058d99.

kernel: dos in crypto_reportstat() function in crypto/crypto_user_stat.c

A memory leak in the crypto_reportstat() function in crypto/crypto_user_stat.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_reportstat_alg() failures, aka CID-c03b04dcdba1.

kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c

An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.

kernel: race condition in vivid_stop_generating_vid_cap(),vivid_stop_generating_vid_out(), sdr_cap_stop_streaming()

An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

Brocade Fabric OS Versions before v7.4.2f, v8.2.2a, v8.1.2j and v8.2.1d could expose external passwords, common secrets or authentication keys used between the switch and an external server.

Brocade Fabric OS Versions before v8.2.2a and v8.2.1d could expose the credentials of the remote ESRS server when these credentials are given as a command line option when configuring the ESRS client.

Host Header Injection vulnerability in the http management interface in Brocade Fabric OS versions before v9.0.0 could allow a remote attacker to exploit this vulnerability by injecting arbitrary HTTP headers

A vulnerability in the management interface in Brocade Fabric OS Versions before Brocade Fabric OS v9.0.0 could allow a remote attacker to perform a denial of service attack on the vulnerable host.

A Reflective XSS Vulnerability in HTTP Management Interface in Brocade Fabric OS versions before Brocade Fabric OS v9.0.0, v8.2.2c, v8.2.1e, v8.1.2k, v8.2.0_CBN3, v7.4.2g could allow authenticated attackers with access to the web interface to hijack a user’s session and take over the account.

A vulnerability in the Brocade Webtools firmware update section of Brocade Fabric OS before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow remote authenticated attackers to execute arbitrary commands.

A vulnerability in Secure Shell implementation of Brocade Fabric OS versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow a local attacker to provide arbitrary environment variables, and bypass the restricted configuration shell.

A vulnerability in the proxy service of Brocade Fabric OS versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow remote unauthenticated attackers to obtain sensitive information and possibly cause a denial of service attack.

A Vulnerability in the supportsave command of Brocade Fabric OS command line interface (CLI) versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow a local attacker to escape the restricted shell and, gain root access.

A Vulnerability in the help command of Brocade Fabric OS command line interface (CLI) versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow a local attacker to escape the restricted shell and, gain root access.
