ansible: atomic_move primitive sets permissive permissions

A flaw was found in Ansible Engine when a file is moved using atomic_move primitive as the file mode cannot be specified. This sets the destination files world-readable if the destination file does not exist and if the file exists, the file could be changed to have less restrictive permissions before the move. This could lead to the disclosure of sensitive data. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.

ansible: path injection on dest parameter in fetch module

A flaw was found in the Ansible Engine when the fetch module is used. An attacker could intercept the module, inject a new path, and then choose a new destination path on the controller node. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.

ansible: insecure temporary directory when running become_user from become directive

A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask 77 && mkdir -p <dir>"; this operation does not fail if the directory already exists and is owned by another user. An attacker could take advantage to gain control of the become user as the target directory can be retrieved by iterating '/proc/<pid>/cmdline'.

libssh: denial of service when handling AES-CTR (or DES) ciphers

A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability.

resteasy: Improper validation of response header in MediaTypeHeaderDelegate.java class

A flaw was found in all resteasy 3.x.x versions prior to 3.12.0.Final and all resteasy 4.x.x versions prior to 4.6.0.Final, where an improper input validation results in returning an illegal header that integrates into the server's response. This flaw may result in an injection, which leads to unexpected behavior when the HTTP response is constructed.

The find_color_or_error function in gifsicle 1.92 contains a NULL pointer dereference.

graphviz: off-by-one in parse_reclbl() in lib/common/shapes.c

Buffer Overflow in Graphviz Graph Visualization Tools from commit ID f8b9e035 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by loading a crafted file into the "lib/common/shapes.c" component.

qt: buffer over-read in read_xbm_body in gui/image/qxbmhandler.cpp

An issue was discovered in Qt through 5.12.9, and 5.13.x through 5.15.x before 5.15.1. read_xbm_body in gui/image/qxbmhandler.cpp has a buffer over-read.

wireshark: Kafka protocol dissector could crash (wnpa-sec-2020-10)

In Wireshark 3.2.0 to 3.2.5, the Kafka protocol dissector could crash. This was addressed in epan/dissectors/packet-kafka.c by avoiding a double free during LZ4 decompression.

radare2 4.5.0 misparses signature information in PE files, causing a segmentation fault in r_x509_parse_algorithmidentifier in libr/util/x509.c. This is due to a malformed object identifier in IMAGE_DIRECTORY_ENTRY_SECURITY.

Firejail through 0.9.62 mishandles shell metacharacters during use of the --output or --output-stderr option, which may lead to command injection.

Firejail through 0.9.62 does not honor the -- end-of-options indicator after the --output option, which may lead to command injection.

scm/define-stencil-commands.scm in LilyPond through 2.20.0, and 2.21.x through 2.21.4, when -dsafe is used, lacks restrictions on embedded-ps and embedded-svg, as demonstrated by including dangerous PostScript code.

golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs

Go before 1.13.15 and 14.x before 1.14.7 can have an infinite read loop in ReadUvarint and ReadVarint in encoding/binary via invalid inputs.

binutils: use-after-free in bfd_hash_lookup could result in DoS

A use after free issue exists in the Binary File Descriptor (BFD) library (aka libbfd) in GNU Binutils 2.34 in bfd_hash_lookup, as demonstrated in nm-new, that can cause a denial of service via a crafted file.

radare2 4.5.0 misparses DWARF information in executable files, causing a segmentation fault in parse_typedef in type_dwarf.c via a malformed DW_AT_name in the .debug_info section.

kernel: information exposure in drivers/char/random.c and kernel/time/timer.c

The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.

perl-App-cpanminus: Bypass of verification of signatures in CHECKSUMS files

The App::cpanminus package 1.7044 for Perl allows Signature Verification Bypass.

A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length.

Roundcube Webmail before 1.3.15 and 1.4.8 allows stored XSS in HTML messages during message display via a crafted SVG document. This issue has been fixed in 1.4.8 and 1.3.15.
