Amazon Linux 2 : ghostscript (ALAS-2018-1088)

It was discovered that the ghostscript .shfill operator did not properly validate certain types. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript...

Amazon Linux 2 : kernel (ALAS-2018-1086)

A security flaw was found in the chapservercomputemd5 function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The atta...

Amazon Linux 2 : openssh (ALAS-2018-1075)

OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.CVE-2018-15473 C Tenable Network...

Amazon Linux 2 : postgresql (ALAS-2018-1080)

A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq were used with 'host' or 'hostaddr' connection parameters from untrusted input, attackers could bypass client-side...

Amazon Linux 2 : bind (ALAS-2018-1082)

A denial of service flaw was discovered in bind versions that include the 'deny-answer-aliases' feature. This flaw may allow a remote attacker to trigger an INSIST assert in named leading to termination of the process and a denial of service condition.CVE-2018-5740 %NASLMINLEVEL 70300 C Tenable...
