The cache action in action/cache.py in MoinMoin through 1.9.10 allows directory traversal through a crafted HTTP request. An attacker who can upload attachments to the wiki can use this to achieve remote code execution.

python-flask-cors: allows ../ directory traversal to access private resources

An issue was discovered in Flask-CORS (aka CORS Middleware for Flask) before 3.0.9. It allows ../ directory traversal to access private resources because resource matching does not ensure that pathnames are in a canonical format.

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

An issue was discovered in LemonLDAP::NG through 2.0.8, when NGINX is used. An attacker may bypass URL-based access control to protected Virtual Hosts by submitting a non-normalized URI. This also affects versions before 0.5.2 of the "Lemonldap::NG handler for Node.js" package.

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.

kernel: Reassembling fragments encrypted under different keys

The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.

kernel: Fragmentation cache not cleared on reconnection

The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.

dovecot: IMAP hibernation function allows mail access

An issue was discovered in Dovecot before 2.3.13. By using IMAP IDLE, an authenticated attacker can trigger unhibernation via attacker-controlled parameters, leading to access to other users' email messages (and path disclosure).

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

Icinga Icinga Web2 2.0.0 through 2.6.4, 2.7.4 and 2.8.2 has a Directory Traversal vulnerability which allows an attacker to access arbitrary files that are readable by the process running Icinga Web 2. This issue is fixed in Icinga Web 2 in v2.6.4, v2.7.4 and v2.8.2.

SNMPTT before 1.4.2 allows attackers to execute shell code via EXEC, PREXEC, or unknown_trap_exec.

QEMU: use-after-free in TCG accelerator can lead to local privilege escalation

An issue was discovered in TCG Accelerator in QEMU 4.2.0, allows local attackers to execute arbitrary code, escalate privileges, and cause a denial of service (DoS). Note: This is disputed as a bug and not a valid security issue by multiple third parties.

poppler: uncontrolled recursion in pdfinfo and pdftops

Uncontrolled Recursion in pdfinfo, and pdftops in poppler 0.89.0 allows remote attackers to cause a denial of service via crafted input.

Multiple Cross Site Scripting (XSS) vulneratiblities exist in Cacti 1.2.12 in (1) reports_admin.php, (2) data_queries.php, (3) data_input.php, (4) graph_templates.php, (5) graphs.php, (6) reports_admin.php, and (7) data_input.php.

c-ares: Heap buffer over read in ares_parse_soa_reply

Buffer overflow vulnerability in c-ares before 1_16_1 thru 1_17_0 via function ares_parse_soa_reply in ares_parse_soa_reply.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_dict_set function in dict.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the wtvfile_open_sector function in wtvdec.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_frame_pool_get function in framepool.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the avpriv_float_dsp_allocl function in libavutil/float_dsp.c.
