A flaw was found in the Python tarfile module. Extracting a crafted TAR archive with the tarfile.extract or tarfile.extractall functions could lead to a directory traversal vulnerability, resulting in overwrite of arbitrary files.

Impact The HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs.

Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5.

Patches The issue has been resolved in lxml 4.6.5.

Workarounds None.

References The issues are tracked under the report IDs GHSL-2021-1037 and GHSL-2021-1038.

A buffer overflow issue was addressed with improved memory handling. This issue is fixed in macOS Mojave 10.14.6, Security Update 2019-004 High Sierra, Security Update 2019-004 Sierra. An attacker in a privileged network position may be able to execute arbitrary code.

Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from 5.10.0-60.18.0 before 5.10.0-183.0.0.

In the Linux kernel before 6.4.12 amdgpucswaitallfences in drivers/gpu/drm/amd/amdgpu/amdgpucs.c has a fence use-after-free.

A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation.

The nftverdictinit() function allows positive values as drop error within the hook verdict, and hence the nfhookslow() function can cause a double free vulnerability when NFDROP is issued with a drop error which resembles NFACCEPT.

We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.

A heap-based buffer overflow was discovered in in libcups's ppdFindOption() function in ppd-mark.c:430. The issue can be reproduced by loading a crafted ppd file and calling the ppdMarkDefaults() libcups API function.

A flaw was found in the Linux kernel. It is possible to overflow a perfevent's readsize, causing an out-of-bounds write in perfreadgroup(). The check meant to prevent such an overflow in perfeventvalidatesize() does not account for groups of events with mixed readformat values. The flaw can be triggered with events created with PERFFORMATGROUP or events added with PERFFORMATGROUP after some preconditions.

The bug was introduced around fa8c269353d5 ("perf/core: Invert perfreadgroup() loops"). Fixes: a723968c0ed3 ("perf: Fix u16 overflows").

A buffer overflow vulnerability in the function |formatlogline| could allow remote attackers to cause a denial-of-service(DoS) on the affected system (not verified for possible arbitrary code execution). Exploitation of the vulnerability can be triggered when the configuration file |cupsd.conf| sets the value of |loglevel |to |DEBUG|.

An issue was discovered in drivers/usb/storage/eneub6250.c for the ENE UB6250 reader driver in the Linux kernel before 6.2.5. An object could potentially extend beyond the end of an allocation.

An out-of-bounds memory read flaw was found in receiveencryptedstandard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service.

Accounts. A privacy issue was addressed with improved private data redaction for log entries.

In the Linux kernel before 6.4.5 drivers/gpu/drm/drmatomic.c has a use-after-free during a race condition between a nonblocking atomic commit and a driver unload.

A race condition was found in the GSM 0710 tty multiplexor (drivers/tty/ngsm.c) in the Linux kernel. The flaw occurs when two threads execute the GSMIOCSETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled and leads to a use-after-free on a struct gsmdlci while restarting the gsm mux. A local unprivileged user could use this vulnerability to escalate their privileges on the system.

IBM QRadar SIEM 7.5 could allow a privileged user to configure user management that would disclose unintended sensitive information across tenants. IBM X-Force ID: 284575.

A logic issue was addressed with improved state management. This issue is fixed in Security Update 2022-003 Catalina, macOS Monterey 12.3, macOS Big Sur 11.6.5. An application may be able to gain elevated privileges.

A vulnerability was found in OpenPrinting CUPS. Unauthorized users are permitted to fetch documents over local or remote networks, leading to confidentiality breach.

A NULL pointer dereference issue was found in the Linux kernel's vmwgfx driver in vmwcmddxdefinequery. Systems making use of the vmwgfx driver are potentially affected by this flaw. Exploiting the bug would require an attacker to have access to either /dev/dri/card0 or /dev/dri/rendererD128 and be able to issue an ioctl() on the resulting file descriptor. Under certain circumstances a local unprivileged user could use this flaw to crash the system, causing a denial of service.

Reference: https://bugzilla.openanolis.cn/showbug.cgi?id=2073

An integer overflow vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfxexecbuf.c in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).

An issue was discovered in lxml before 4.2.5. lxml/html/clean.py in the lxml.html.clean module does not remove javascript: URLs that use escaping, allowing a remote attacker to conduct XSS attacks, as demonstrated by "j a v a s c r i p t:" in Internet Explorer. This is a similar issue to CVE-2014-3146.

Incomplete blacklist vulnerability in the lxml.html.clean module in lxml before 3.3.5 allows remote attackers to conduct cross-site scripting (XSS) attacks via control characters in the link scheme to the cleanhtml function.

A memory leak problem was found in ctnetlinkcreateconntrack in net/netfilter/nfconntracknetlink.c in the Linux Kernel. In this flaw a local attacker with CAPNETADMIN privilege may cause a denial of service (DoS) attack due to a refcount overflows.

An input validation issue was addressed with improved memory handling. This issue is fixed in macOS Big Sur 11.1, Security Update 2020-001 Catalina, Security Update 2020-007 Mojave. A malicious application may be able to read restricted memory.

Canonical cloud-init could allow a local authenticated attacker to obtain sensitive information, caused by the storage of sensitive data in the log files. By gaining access to the log files, an attacker could exploit this vulnerability to obtain hashed passwords information, and use this information to launch further attacks against the affected system.
