Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU31436
Risk: Medium
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2015-8985
CWE-ID:
CWE-19 - Data Handling

DescriptionThe vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The pop_fail_stack function in the GNU C Library (aka glibc or libc6) allows context-dependent attackers to cause a denial of service (assertion failure and application crash) via vectors related to extended regular expression processing.
MitigationUpdate the affected packages.

EUVDB-ID: #VU32268
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-6263
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data.
MitigationUpdate the affected packages.

EUVDB-ID: #VU16149
Risk: Low
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-19591
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to an invalid 'ifname' parameter to __if_nametoindex() in 'sysdeps/unix/sysv/linux/if_index.c'. A remote attacker can invoke a call to the getaddrinfo() function with a 'node' parameter, consume excessive memory and cause the service to crash.
MitigationUpdate the affected packages.
