Gentoo: GLSA-202007-31 High Severity: Icinga Root Privilege Escalation

Icinga installs files with insecure permissions allowing root privilege escalation.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202007-31 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: Icinga: Root privilege escalation Date: July 27, 2020 Bugs: #638186 ID: 202007-31 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= Icinga installs files with insecure permissions allowing root privilege escalation. Background ========= Icinga is an open source computer system and network monitoring application. It was originally created as a fork of the Nagios system monitoring application in 2009. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/icinga < 1.14.2 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers. Description ========== It was discovered that Icinga's installed files have insecure permissions, possibly allowing root privilege escalation. Impact ===== A local attacker could escalate privileges to root. Workaround ========= There is no known workaround at this time. Resolution ========= Gentoo has discontinued support for Icinga. We recommend that usersunmerge Icinga: # emerge --unmerge "net-analyzer/icinga" NOTE: The Gentoo developer(s) maintaining Icinga havediscontinued support at this time. It may be possible that a new Gentoo developer will update Icinga at a later date. The natural replacement is Icinga 2 (net-analyzer/icinga2).

SUSE Security Update: Security update for the Linux Kernel ______________________________________________________________________________ Announcement ID: SUSE-SU-2018:3088-1 Rating: important References: #1045538 #1048185 #1050381 #1050431 #1057199 #1060245 #1064861 #1068032 #1080157 #1087081 #1092772 #1092903 #1093666 #1096547 #1098822 #1099922 #1100132 #1100705 #1102517 #1102870 #1103119 #1104481 #1104684 #1104818 #1104901 #1105100 #1105322 #1105348 #1105536 #1105723 #1106095 #1106105 #1106199 #1106202 #1106206 #1106209 #1106212 #1106369 #1106509 #1106511 #1106609 #1106886 #1106930 #1106995 #1107001 #1107064 #1107071 #1107650 #1107689 #1107735 #1107949 #1108096 #1108170 #1108823 #1108912 Cross-References: CVE-2018-10902 CVE-2018-10940 CVE-2018-12896 CVE-2018-14617 CVE-2018-14634 CVE-2018-14734 CVE-2018-15572 CVE-2018-15594 CVE-2018-16276 CVE-2018-16658 CVE-2018-6554 CVE-2018-6555 Affected Products: SUSE Linux Enterprise Real Time Extension 11-SP4 SUSE Linux Enterprise Debuginfo 11-SP4 ______________________________________________________________________________ An update that solves 12 vulnerabilities and has 43 fixes is now available. Description: The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912) - CVE-2018-14617: Prevent NULL pointerdereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870) - CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095) - CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922) - CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903) - CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689) - CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511) - CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509) - CVE-2018-15594: Ensure correct handling of indirect calls, to prevent attackers for conducting Spectre-v2 attacks against paravirtual guests (bsc#1105348) - CVE-2018-15572: Thespectre_v2_select_mitigation function did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517) - CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322). - CVE-2018-14734: ucma_leave_multicast accessed a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bsc#1103119) The following non-security bugs were fixed: - ACPI: APEI / ERST: Fix missing error handling in erst_reader() (bsc#1045538). - ALSA: fm801: propagate TUNER_ONLY bit when autodetected (bsc#1045538). - ALSA: pcm: Fix snd_pcm_hw_params struct copy in compat mode (bsc#1045538). -

Red Hat: RHSA-2007:0937-01 Critical: Root Privilege Escalation Issue

Updated kernel packages that fix a security issue in the Red Hat Enterprise Linux 4 kernel are now available. A flaw was found in the IA32 system call emulation provided on AMD64 and Intel 64 platforms. An improperly validated 64-bit value could be stored in the %RAX register, which could trigger an out-of-bounds system call table access. An untrusted local user could exploit this flaw to run code in the kernel (ie a root privilege escalation). . - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2007:0937-01 Advisory URL: https://access.redhat.com/errata/RHSA-2007:0937.html Issue date: 2007-09-27 Updated on: 2007-09-27 Product: Red Hat Enterprise Linux CVE Names: CVE-2007-4573 - ---------------------------------------------------------------------1.
