atop: symlink attack possible due to insecure tempfile handling

avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE), not the upstream Avahi product.

The save function in br/prefmanager.d in projectl 1.001 creates a projectL.prf file in the current working directory, which allows local users to overwrite arbitrary files via a symlink attack.

The write_array_file function in utils/include.pl in GForge 4.5.14 updates configuration files by truncating them to zero length and then writing new data, which might allow attackers to bypass intended access restrictions or have unspecified other impact in opportunistic circumstances.

Inappropriate implementation in installer in Google Chrome prior to 84.0.4147.125 allowed a local attacker to potentially elevate privilege via a crafted filesystem.

KDE before 3.3.0 does not properly handle when certain symbolic links point to "stale" locations, which could allow local users to create or truncate arbitrary files.

Insufficient data validation in installer in Google Chrome prior to 86.0.4240.183 allowed a local attacker to potentially elevate privilege via a crafted filesystem.

systemd-tmpfiles in systemd before 237 attempts to support ownership/permission changes on hardlinked files even if the fs.protected_hardlinks sysctl is turned off, which allows local users to bypass intended access restrictions via vectors involving a hard link to a file for which the user lacks write access, as demonstrated by changing the ownership of the /etc/passwd file.

In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. NOTE: exploitation might be impractical without the CAP_SYS_ADMIN capability.

Unspecified vulnerability in Oracle Sun Solaris 11.3 allows local users to affect confidentiality, integrity, and availability via unknown vectors.

Unknown vulnerability in Oracle Label Security in Oracle 8.1.7 and 9.0.1, when audit functionality, SET_LABEL, or SQL*Predicate is being used, allows local users to gain additional access.

dbsnmp in Oracle 8.1.6 and 8.1.7 uses the ORACLE_HOME environment variable to find and execute the dbsnmp program, which allows local users to execute arbitrary programs by pointing the ORACLE_HOME to an alternate directory that contains a malicious version of dbsnmp.

Buffer overflow in glob function of glibc allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a glob pattern that ends in a brace "{" character.

Insufficient validation of environment variables in the telnet client supplied in Junos OS can lead to stack-based buffer overflows, which can be exploited to bypass veriexec restrictions on Junos OS. A stack-based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers. This issue only affects the telnet client — accessible from the CLI or shell — in Junos OS. Inbound telnet services are not affected by this issue. This issue affects: Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S13; 12.3X48 versions prior to 12.3X48-D80; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D237, 15.1X53-D496, 15.1X53-D591, 15.1X53-D69; 16.1 versions prior to 16.1R3-S11, 16.1R7-S4; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R2-S7, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S6, 17.4R2-S3, 17.4R3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S3; 18.2 versions prior to 18.2R1-S5, 18.2R2-S2, 18.2R3; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3, 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2.

Buffer overflow in Oracle 8.1.5 applications such as names, namesctl, onrsd, osslogin, tnslsnr, tnsping, trcasst, and trcroute possibly allow local users to gain privileges via a long ORACLE_HOME environmental variable.

The snprintf function in the db library 1.85.4 ignores the size parameter, which could allow attackers to exploit buffer overflows that would be prevented by a properly implemented snprintf.

Oracle Database Assistant 1.0 in Oracle 8.0.3 Enterprise Edition stores the database master password in plaintext in the spoolmain.log file when a new database is created, which allows local users to obtain the password from that file.

Buffer overflow in bash 2.0.0, 1.4.17, and other versions allows local attackers to gain privileges by creating an extremely large directory name, which is inserted into the password prompt via the \w option in the PS1 environmental variable when another user changes into that directory.

dbsnmp in Oracle Intelligent Agent allows local users to gain privileges by setting the ORACLE_HOME environmental variable, which dbsnmp uses to find the nmiconf.tcl script.

mysqld in MySQL 3.21 creates log files with world-readable permissions, which allows local users to obtain passwords for users who are added to the user database.

An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c.

The Linux kernel before 2.6.32.4 allows local users to gain privileges or cause a denial of service (panic) by calling the (1) mmap or (2) mremap function, aka the "do_mremap() mess" or "mremap/mmap mess."

mount.ecryptfs_private.c in eCryptfs-utils does not validate mount destination filesystem types, which allows local users to gain privileges by mounting over a nonstandard filesystem, as demonstrated by /proc/$pid.

The CUPS AppArmor profile incorrectly confined the dnssd backend due to use of hard links. A local attacker could possibly use this issue to escape confinement. This flaw affects versions prior to 2.2.7-1ubuntu2.1 in Ubuntu 18.04 LTS, prior to 2.2.4-7ubuntu3.1 in Ubuntu 17.10, prior to 2.1.3-4ubuntu0.5 in Ubuntu 16.04 LTS, and prior to 1.7.2-0ubuntu1.10 in Ubuntu 14.04 LTS.

The oratclsh interpreter in Oracle 8.x Intelligent Agent for Unix allows local users to execute Tcl commands as root.

The Linux kernel 4.15 has a Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user.

Go before 1.8.7, Go 1.9.x before 1.9.4, and Go 1.10 pre-releases before Go 1.10rc2 allow "go get" remote command execution during source code build, by leveraging the gcc or clang plugin feature, because -fplugin= and -plugin= arguments were not blocked.

The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
