checkinstall 1.6.2, when used to create a package that contains a symlink, may trigger the creation of a mode 0777 executable file.

CGI implementation in Yaws web server versions 1.81 to 2.0.7 is vulnerable to OS command injection.

ark: crafted TAR archive with symlinks can install files outside the extraction directory

In KDE Ark before 20.08.1, a crafted TAR archive with symlinks can install files outside the extraction directory, as demonstrated by a write operation to a user's home directory.

squid: Improper input validation could result in a DoS

Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF.

django: permission escalation in intermediate-level directories of the file system cache on Python 3.7+

An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). The intermediate-level directories of the filesystem cache had the system's standard umask rather than 0o077.

django: incorrect permissions on intermediate-level directories on Python 3.7+

An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories created in the process of uploading files. It was also not applied to intermediate-level collected static directories when using the collectstatic management command.

kernel: umask not applied on filesystem without ACL support

In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.

WebDAV implementation in Yaws web server versions 1.81 to 2.0.7 is vulnerable to XXE injection.

libslirp: use after free vulnerability cause a denial of service.

A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service.

A carefully crafted or corrupt PSD file can cause an infinite loop in Apache Tika's PSDParser in versions 1.0-1.23.

tika: excessive memory usage in PSDParser

A carefully crafted or corrupt PSD file can cause excessive memory usage in Apache Tika's PSDParser in versions 1.0-1.23.

ant: insecure temporary file vulnerability

Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.

httpd: mod_proxy_ftp use of uninitialized value

In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server.

httpd: mod_rewrite configurations vulnerable to open redirect

In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL.

ceph: header-splitting in RGW GetObject has a possible XSS

A flaw was found in the Ceph Object Gateway, where it supports request sent by an anonymous user in Amazon S3. This flaw could lead to potential XSS attacks due to the lack of proper neutralization of untrusted input.

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.

ceph: connection leak in the RGW Beast front-end permits a DoS against the RGW server

A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSE_WAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system.

gnome-shell: Password from logged-out user may be shown on login screen

An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4. When logging out of an account, the password box from the login dialog reappears with the password still visible. If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.)

ghostscript: division by zero in dot24_print_page() in devices/gdevdm24.c could result in a DoS

A division by zero vulnerability in dot24_print_page() in devices/gdevdm24.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

ghostscript: buffer overflow in lxm5700m_print_page() in devices/gdevlxm.c could result in a DoS

A buffer overflow vulnerability in lxm5700m_print_page() in devices/gdevlxm.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted eps file. This is fixed in v9.51.
