OpenSSH: Client buffer-overflow when using roaming connections

The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings.

OpenSSH: Client Information leak due to use of roaming connection feature

The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key.

A remote code execution vulnerability exists in the WebAdmin of Sophos SG UTM before v9.705 MR5, v9.607 MR7, and v9.511 MR11

The Frontend component in Sophos UTM with firmware 9.405-5 and earlier allows local administrators to obtain sensitive password information by reading the "value" field of the SMTP user settings in the notifications configuration tab.

Memory leak in the TCP stack in the kernel in Sophos UTM before 9.109 allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors.

glibc: getaddrinfo stack-based buffer overflow

Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module.

dhcp: UDP payload length not properly checked

ISC DHCP 4.x before 4.1-ESV-R12-P1, 4.2.x, and 4.3.x before 4.3.3-P1 allows remote attackers to cause a denial of service (application crash) via an invalid length field in a UDP IPv4 packet.

The Frontend component in Sophos UTM with firmware 9.405-5 and earlier allows local administrators to obtain sensitive password information by reading the "value" field of the proxy user settings in "system settings / scan settings / anti spam" configuration tab.

Cross-site scripting (XSS) vulnerability in the UserPortal page in SOPHOS UTM before 9.353 allows remote attackers to inject arbitrary web script or HTML via the lang parameter.

Cross-site scripting (XSS) vulnerability in the Backup/Restore component in WebAdmin in Astaro Security Gateway before 8.305 allows remote attackers to inject arbitrary web script or HTML via the "Comment (optional)" field.

Unspecified vulnerability in WebAdmin in Sophos UTM (aka Astaro Security Gateway) before 9.105 has unknown impact and attack vectors.

Confd log files contain local users', including root’s, SHA512crypt password hashes with insecure access permissions. This allows a local attacker to attempt off-line brute-force attacks against these password hashes in Sophos UTM before version 9.710.

A post-auth SQL injection vulnerability in the Mail Manager potentially allows an authenticated attacker to execute code in Sophos UTM before version 9.710.

An authenticated user could potentially execute code via an SQLi vulnerability in the user portal of SG UTM before version 9.708 MR8.

Stored XSS can execute as administrator in quarantined email detail view in Sophos UTM before version 9.706.
