Amazon Linux 2 : kernel (ALAS-2019-1280)

A buffer overflow due to a singed-unsigned comparsion was found in hidpprocessreport in the net/bluetooth/hidp/core.c in the Linux kernel. The buffer length is an unsigned int but gets cast to a signed int which in certain conditions can lead to a system panic and a denial-of-service. CVE-2018-93...

Amazon Linux 2 : edk2 (ALAS-2019-1290)

Insufficient memory write check in SMM service for EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via local access. CVE-2018-12182 Stack overflow in XHCI for EDK II may allow an unauthenticated user to...

Amazon Linux 2 : kernel (ALAS-2019-1279)

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location ...

Amazon Linux 2 : python (ALAS-2019-1291)

urllib in Python 2.7.16 supports the localfile: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen'localfile:///etc/passwd' call. CVE-2019-9948 C Tenable Network Security, Inc. The descriptiv...

Amazon Linux 2 : oniguruma (ALAS-2019-1288)

A use-after-free in onignewdeluxe in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte...
