Resolution ========== Upgrade to 0.13.66-2. # pacman -Syu "zziplib>=0.13.66-2" The problems have been fixed upstream in version 0.13.66. Workaround ========== None. Description =========== - CVE-2017-5974 (arbitrary code execution) Heap-based buffer overflow in the __zzip_get32 function in fetch.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (crash) via a crafted ZIP file. - CVE-2017-5975 (arbitrary code execution) Heap-based buffer overflow in the __zzip_get64 function in fetch.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (crash) via a crafted ZIP file. - CVE-2017-5976 (arbitrary code execution) Heap-based buffer overflow in the zzip_mem_entry_extra_block function in memdisk.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (crash) via a crafted ZIP file. - CVE-2017-5979 (denial of service) The prescan_entry function in fseeko.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted ZIP file. - CVE-2017-5981 (denial of service) seeko.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (assertion failure and crash) via a crafted ZIP file. Impact ====== A remote attacker is able to crash the target process or execute arbitrary code on the host by providing a malicious file.

[arch-security] [ASA-201705-14] git: access restriction bypass
by Remi Gacogne 12 May '17

12 May '17

Arch Linux Security Advisory ASA-201705-14 ========================================== Severity: High Date : 2017-05-12 CVE-ID : CVE-2017-8386 Package : git Type : access restriction bypass Remote : Yes Link : https://security.archlinux.org/AVG-267 Summary ======= The package git before version 2.13.0-1 is vulnerable to access restriction bypass. Resolution ========== Upgrade to 2.13.0-1. # pacman -Syu "git>=2.13.0-1" The problem has been fixed upstream in version 2.13.0. Workaround ========== None. Description =========== A security issue has been found in git < 2.12.3, allowing a remote restricted user to execute an interactive pager on the server by causing it to spawn "git upload-pack --help". This is only an issue for servers running the "git-shell" restricted login shell. Impact ====== A remote attacker can use the interactive pager commands to access and modify arbitrary files on the affected host. If the login shell used is not git-shell, a remote attacker might also be able to run arbitrary commands on the affected host.

Arch Linux Security Advisory ASA-201705-13 ========================================== Severity: High Date : 2017-05-10 CVE-ID : CVE-2017-8422 Package : kdelibs Type : privilege escalation Remote : No Link : https://security.archlinux.org/AVG-270 Summary ======= The package kdelibs before version 4.14.32-1 is vulnerable to privilege escalation. Resolution ========== Upgrade to 4.14.32-1. # pacman -Syu "kdelibs>=4.14.32-1" The problem has been fixed upstream in version 4.14.32. Workaround ========== None. Description =========== KAuth <= 5.33.0 contains a logic flaw in which the service invoking dbus is not properly checked. This allows spoofing the identity of the caller and with some carefully crafted calls can lead to gaining root from an unprivileged account. Impact ====== A local, unprivileged attacker can escalate privileges to become root on the affected host.

Arch Linux Security Advisory ASA-201705-11 ========================================== Severity: High Date : 2017-05-10 CVE-ID : CVE-2017-8849 Package : smb4k Type : privilege escalation Remote : No Link : https://security.archlinux.org/AVG-268 Summary ======= The package smb4k before version 2.0.0-2 is vulnerable to privilege escalation. Resolution ========== Upgrade to 2.0.0-2. # pacman -Syu "smb4k>=2.0.0-2" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== Smb4k <= 2.0.0 contains a logic flaw in which mount helper binary does not properly verify the mount command it is being asked to run. This allows calling any other binary as root since the mount helper is typically installed as suid. Impact ====== A local, unprivileged attacker can escalate privileges to become root on the affected host.

Arch Linux Security Advisory ASA-201705-6 ========================================= Severity: Medium Date : 2017-05-07 CVE-ID : CVE-2017-8779 Package : lib32-libtirpc Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-263 Summary ======= The package lib32-libtirpc before version 1.0.1-2 is vulnerable to denial of service. Resolution ========== Upgrade to 1.0.1-2. # pacman -Syu "lib32-libtirpc>=1.0.1-2" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== It was found that libtirpc and libntirpc fails to free a buffer allocated for parsing XDR blocks when parsing fails due to insufficient input data being available.
