Low: curl

Issue Overview: curl is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curlntlmcoremknthash multiplies the length of the password by two SUM to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used ...

Medium: python3

Issue Overview: Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by contructing an XML document that would cause pathological hash collisions in Expat's internal data...

Medium: glibc

Issue Overview: A buffer overflow has been discovered in the GNU C Library aka glibc or libc6 in the mempcpyavx512novzeroupper function when particular conditions are met. An attacker could use this vulnerability to cause a denial of service or potentially execute code.CVE-2018-11237 Affected...

Amazon Linux 2 : fuse (ALAS-2018-1123)

A vulnerability was discovered in fuse. When SELinux is active, fusermount is vulnerable to a restriction bypass. This allows non-root users to mount a FUSE file system with the 'allowother' mount option regardless of whether 'userallowother' is set in the fuse configuration. An attacker may use...

Amazon Linux 2 : wpa_supplicant (ALAS-2018-1122)

An issue was discovered in rsnsupp/wpa.c in wpasupplicant 2.0 through 2.6. Under certain conditions, the integrity of EAPOL-Key messages is not checked, leading to a decryption oracle. An attacker within range of the Access Point and client can abuse the vulnerability to recover sensitive...

Amazon Linux 2 : xerces-c (ALAS-2018-1124)

A stack exhaustion flaw was found in the way Xerces-C XML parser handled deeply nested DTDs. An attacker could potentially use this flaw to crash an application using Xerces-C by tricking it into processing specially crafted data.CVE-2016-4463 C Tenable Network Security, Inc. The descriptive text...

Amazon Linux 2 : wget (ALAS-2018-1121)

A cookie injection flaw was found in wget. An attacker can create a malicious website which, when accessed, overrides cookies belonging to arbitrary domains.CVE-2018-0494 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from Amazon Linux 2...

Amazon Linux 2 : gnutls (ALAS-2018-1120)

It was found that GnuTLS's implementation of HMAC-SHA-256 was vulnerable to Lucky Thirteen-style attack. A remote attacker could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets.CVE-2018-10844 It was foun...

Medium: fuse

Issue Overview: A vulnerability was discovered in fuse. When SELinux is active, fusermount is vulnerable to a restriction bypass. This allows non-root users to mount a FUSE file system with the 'allowother' mount option regardless of whether 'userallowother' is set in the fuse configuration. An...

Amazon Linux 2 : spamassassin (ALAS-2018-1103)

A flaw was found in the way SpamAssassin processes HTML email containing unclosed HTML tags. A carefully crafted mail message could cause SpamAssassin to consume significant resources. If a large number of these messages are sent, a denial of service could occur potentially delaying or preventing...

Amazon Linux 2 : openssl (ALAS-2018-1102)

During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This...

Amazon Linux 2 : tomcat (ALAS-2018-1105)

An improper handing of overflow in the UTF-8 decoder with supplementary characters can lead to an infinite loop in the decoder causing a Denial of Service.CVE-2018-1336 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from Amazon Linux 2...

Amazon Linux 2 : kernel (ALAS-2018-1100)

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel. An attacker with a local account can trick the stack unwinder code to leak stack contents to userspace. The fix allows only root to inspect the kernel stack of an arbitrary task.CVE-2018-17972 A...

Amazon Linux 2 : mod_http2 (ALAS-2018-1104)

In Apache HTTP Server, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.CVE-2018-11763 C Tenable...

Amazon Linux 2 : nss (ALAS-2018-1095)

A flaw was found in the way NSS responded to an SSLv2-compatible ClientHello with a ServerHello that had an all-zero random.
