A flaw was found in rsync. When using the --safe-links option, rsync fails to properly verify if a symbolic link destination contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.

A path traversal vulnerability exists in rsync. It stems from behavior enabled by the --inc-recursive option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the --inc-recursive option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.

A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file from the client's machine. This issue occurs when files are being copied from a client to a server. During this process, the rsync server will send checksums of local data to the client to compare with in order to determine what data needs to be sent to the server. By sending specially constructed checksum values for arbitrary files, an attacker may be able to reconstruct the data of those files byte-by-byte based on the responses from the client.

A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.

A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAXDIGESTLEN exceeds the fixed SUMLENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.

Soko if the code that powers packages.gentoo.org. Prior to version 1.0.2, the two package search handlers, Search and SearchFeed, implemented in pkg/app/handler/packages/search.go, are affected by a SQL injection via the q parameter. As a result, unauthenticated attackers can execute arbitrary SQL queries on https://packages.gentoo.org/. It was also demonstrated that primitive was enough to gain code execution in the context of the PostgreSQL container. The issue was addressed in commit 4fa6e4b619c0362728955b6ec56eab0e0cbf1e23y of version 1.0.2 using prepared statements to interpolate user-controlled data in SQL queries.

Gentoo soko is the code that powers packages.gentoo.org. Versions prior to 1.0.1 are vulnerable to SQL Injection, leading to a Denial of Service. If the user selects (in user preferences) the "Recently Visited Packages" view for the index page, the value of the searchhistory cookie is used as a base64 encoded comma separated list of atoms. These are string loaded directly into the SQL query with atom = '%s' format string. As a result, any user can modify the browser's cookie value and inject most SQL queries. A proof of concept malformed cookie was generated that wiped the database or changed it's content. On the database, only public data is stored, so there is no confidentiality issues to site users. If it is known that the database was modified, a full restoration of data is possible by performing a full database wipe and performing full update of all components. This issue is patched with commit id 5ae9ca83b73. Version 1.0.1 contains the patch. If users are unable to upgrade immediately, the following workarounds may be applied: (1.) Use a proxy to always drop the searchhistory cookie until upgraded. The impact on user experience is low. (2.) Sanitize to the value of searchhistory cookie after base64 decoding it.

USBView 2.1 before 2.2 allows some local users (e.g., ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g., allowany=yes) for pkexec disable the authentication requirement. Code execution can, for example, use the --gtk-module option. This affects Ubuntu, Debian, and Gentoo.

The Gentoo app-backup/burp package before 2.1.32 has incorrect group ownership of the /etc/burp directory, which might allow local users to obtain read and write access to arbitrary files by leveraging access to a certain account for a burp-server.conf change.

The Gentoo app-backup/burp package before 2.1.32 sets the ownership of the PID file directory to the burp account, which might allow local users to kill arbitrary processes by leveraging access to this account for PID file modification before a root script sends a SIGKILL.

The Gentoo net-im/jabberd2 package through 2.6.1 sets the ownership of /var/run/jabber to the jabber account, which might allow local users to kill arbitrary processes by leveraging access to this account for PID file modification before a root script executes a "kill -TERM cat /var/run/jabber/filename.pid" command.

The Gentoo net-im/jabberd2 package through 2.6.1 installs jabberd, jabberd2-c2s, jabberd2-router, jabberd2-s2s, and jabberd2-sm in /usr/bin owned by the jabber account, which might allow local users to gain privileges by leveraging access to this account and then waiting for root to execute one of these programs.

The installation scripts in the Gentoo dev-db/mysql, dev-db/mariadb, dev-db/percona-server, dev-db/mysql-cluster, and dev-db/mariadb-galera packages before 2017-09-29 have chown calls for user-writable directory trees, which allows local users to gain privileges by leveraging access to the mysql account for creation of a link.

The init script in the Gentoo app-admin/logstash-bin package before 5.5.3 and 5.6.x before 5.6.1 has "chown -R" calls for user-writable directory trees, which allows local users to gain privileges by leveraging access to a $LSUSER account for creation of a hard link.

Integer overflow in the trbitfieldEnsureNthBitAlloced function in bitfield.c in Transmission before 2.84 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted peer message, which triggers an out-of-bounds write.

MediaWiki before 1.19.6 and 1.20.x before 1.20.5 allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated by a CDATA section containing valid UTF-7 encoded sequences in a SVG file, which is then incorrectly interpreted as UTF-8 by Chrome and Firefox.

MediaWiki before 1.19.6 and 1.20.x before 1.20.5 does not allow extensions to prevent password changes without using both Special:PasswordReset and Special:ChangePassword, which allows remote attackers to bypass the intended restrictions of an extension that only implements one of these blocks.

Multiple heap-based buffer overflows in Aircrack-ng before 1.1 allow remote attackers to cause a denial of service (crash) and execute arbitrary code via a (1) large length value in an EAPOL packet or (2) long EAPOL packet.

Agostino Sarubbo reported on the oss-security mailing list [1] that, on Gentoo, thttpd log file is world-readable. This could allow an unprivileged user to read the log file.

The default configuration of logrotate on Gentoo Linux uses root privileges to process files in directories that permit non-root write access, which allows local users to conduct symlink and hard link attacks by leveraging logrotate's lack of support for untrusted directories, as demonstrated by directories under /var/log/ for packages.

ZoneMinder 1.23.3 on Gentoo Linux uses 0644 permissions for /etc/zm.conf, which allows local users to obtain the database username and password by reading this file.

Untrusted search path vulnerability in the Gentoo package of Xpdf before 3.02-r2 allows local users to gain privileges via a Trojan horse xpdfrc file in the current working directory, related to an unset SYSTEMXPDFRC macro in a Gentoo build process that uses the poppler library.

The default configuration of Firebird before 2.0.3.12981.0-r6 on Gentoo Linux sets the ISCPASSWORD environment variable before starting Firebird, which allows remote attackers to bypass SYSDBA authentication and obtain sensitive database information via an empty password.

Interpretation conflict in PHP Toolkit before 1.0.1 on Gentoo Linux might allow local users to cause a denial of service (PHP outage) and read contents of PHP scripts by creating a file with a one-letter lowercase alphabetic name, which triggers interpretation of a certain unquoted [a-z] argument as a matching shell glob for this name, rather than interpretation as the literal [a-z] regular-expression string, and consequently blocks the launch of the PHP interpreter within the Apache HTTP Server.

ViewVC before 1.0.5 stores sensitive information under the web root with insufficient access control, which allows remote attackers to read files and list folders under the hidden CVSROOT folder.

ViewVC before 1.0.5 includes "all-forbidden" files within search results that list CVS or Subversion (SVN) commits, which allows remote attackers to obtain sensitive information.

ViewVC before 1.0.5 provides revision metadata without properly checking whether access was intended, which allows remote attackers to obtain sensitive information by reading (1) forbidden pathnames in the revision view, (2) log history that can only be reached by traversing a forbidden object, or (3) forbidden diff view path parameters.

The docert function in ssl-cert.eclass, when used by srccompile or srcinstall on Gentoo Linux, stores the SSL key in a binpkg, which allows local users to extract the key from the binpkg, and causes multiple systems that use this binpkg to have the same SSL key and certificate.

expn in the am-utils and net-fs packages for Gentoo, rPath Linux, and other distributions, allows local users to overwrite arbitrary files via a symlink attack on the expn[PID] temporary file. NOTE: this is the same issue as CVE-2003-0308.1.
