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.

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.

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.

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.

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.

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.

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

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.
