openldap: contrib/slapd-modules/nops/nops.c attempts to free stack buffer allowing remote attackers to cause a denial of service

contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation.

kernel: Salsa20 encryption algorithm does not correctly handle zero-length inputs allowing local attackers to cause denial-of-service

The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.

kernel: HMAC implementation does not validate that the underlying cryptographic hash algorithm is unkeyed allowing local attackers to cause denial-of-service

The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.

The SuSEfirewall2 package before 3.6.312-2.13.1 in SUSE Linux Enterprise (SLE) Desktop 12 SP2, Server 12 SP2, and Server for Raspberry Pi 12 SP2; before 3.6.312.333-3.10.1 in SLE Desktop 12 SP3 and Server 12 SP3; before 3.6_SVNr208-2.18.3.1 in SLE Server 11 SP4; before 3.6.312-5.9.1 in openSUSE Leap 42.2; and before 3.6.312.333-7.1 in openSUSE Leap 42.3 might allow remote attackers to bypass intended access restrictions on the portmap service by leveraging a missing source net restriction for _rpc_ services.

dnsmasq: heap overflow in the code responsible for building DNS replies

Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response.

dnsmasq: stack buffer overflow in the DHCPv6 code

Stack-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DHCPv6 request.

wpa_supplicant: Reinstallation of the pairwise key in the 4-way handshake

glibc: heap/stack gap jumping via unbounded stack allocations

glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.
