Arch Linux Security Advisory ASA-202505-14 ========================================== Severity: High Date : 2025-05-21 CVE-ID : CVE-2025-40775 Package : bind Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-2881 Summary ======= The package bind before version 9.20.9-1 is vulnerable to denial of service. Resolution ========== Upgrade to 9.20.9-1. # pacman -Syu "bind>=9.20.9-1" The problem has been fixed upstream in version 9.20.9. Workaround ========== None. Description =========== When an incoming DNS protocol message includes a Transaction Signature (TSIG), BIND always checks it. If the TSIG contains an invalid value in the algorithm field, BIND immediately aborts with an assertion failure. Impact ====== A remote attacker can send a specially crafted DNS request leading to a denial of service.

Arch Linux Security Advisory ASA-202505-13 ========================================== Severity: High Date : 2025-05-20 CVE-ID : CVE-2025-47905 Package : varnish Type : content spoofing Remote : Yes Link : https://security.archlinux.org/AVG-2879 Summary ======= The package varnish before version 7.7.1-1 is vulnerable to content spoofing. Resolution ========== Upgrade to 7.7.1-1. # pacman -Syu "varnish>=7.7.1-1" The problem has been fixed upstream in version 7.7.1. Workaround ========== None. Description =========== A client-side desync vulnerability can be triggered in Varnish Cache. This vulnerability can be triggered under specific circumstances involving malformed HTTP/1 chunked requests. An attacker can abuse a flaw in Varnish’s handling of chunked transfer encoding which allows certain malformed HTTP/1 requests to exploit improper framing of the message body to smuggle additional requests. Specifically, Varnish incorrectly permits CRLF to be skipped to delimit chunk boundaries. Impact ====== A remote attacker able to send specially crafted HTTP/1 chunked requests can exploit Varnish to smuggle additional requests, potentially leading to information disclosure and allowing incorrect or malicious content to be cached and served to other users.

[ASA-202505-12] go: directory traversal
by Andrea Denisse 20 May '25

20 May '25

Arch Linux Security Advisory ASA-202505-12 ========================================== Severity: Low Date : 2025-05-19 CVE-ID : CVE-2025-22873 Package : go Type : directory traversal Remote : No Link : https://security.archlinux.org/AVG-2878 Summary ======= The package go before version 2:1.24.3-1 is vulnerable to directory traversal. Resolution ========== Upgrade to 2:1.24.3-1. # pacman -Syu "go>=2:1.24.3-1" The problem has been fixed upstream in version 1.24.3. Workaround ========== None. Description =========== It was possible to improperly access the parent directory of a restricted filesystem root created with os.DirFS. Calling Open("../") on such a filesystem could open the parent directory itself, violating expected directory confinement. This escape did not allow access to ancestor directories beyond the parent, nor to files within the parent directory. This behavior has been corrected to return an error for such paths. Impact ====== A local attacker or untrusted component running within a Go application could bypass directory confinement by accessing the parent directory of a restricted os.DirFS root using a "../" path.

[ASA-202505-11] freetype2: arbitrary code execution
by Andrea Denisse 20 May '25

20 May '25

Arch Linux Security Advisory ASA-202505-11 ========================================== Severity: High Date : 2025-05-19 CVE-ID : CVE-2025-27363 Package : freetype2 Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-2877 Summary ======= The package freetype2 before version 2.13.3-3 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 2.13.3-3. # pacman -Syu "freetype2>=2.13.3-3" The problem has been fixed upstream in version 2.13.3. Workaround ========== None. Description =========== An out of bounds write exists in FreeType versions 2.13.0 and below when attempting to parse font subglyph structures related to TrueType GX and variable font files. The vulnerable code assigns a signed short value to an unsigned long and then adds a static value causing it to wrap around and allocate too small of a heap buffer. The code then writes up to 6 signed long integers out of bounds relative to this buffer. This may result in arbitrary code execution. This vulnerability may have been exploited in the wild. Impact ====== A remote attacker that is able to load a specially crafted font file is able to execute arbitrary code on the affected host.

[ASA-202505-10] python-django: denial of service
by Andrea Denisse 20 May '25

20 May '25

Arch Linux Security Advisory ASA-202505-10 ========================================== Severity: Medium Date : 2025-05-19 CVE-ID : CVE-2025-32873 Package : python-django Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-2876 Summary ======= The package python-django before version 5.1.9-1 is vulnerable to denial of service. Resolution ========== Upgrade to 5.1.9-1. # pacman -Syu "python-django>=5.1.9-1" The problem has been fixed upstream in version 5.1.9. Workaround ========== None. Description =========== django.utils.html.strip_tags() would be slow to evaluate certain inputs containing large sequences of incomplete HTML tags. This function is used to implement the striptags template filter, which was thus also vulnerable. django.utils.html.strip_tags() now raises a SuspiciousOperation exception if it encounters an unusually large number of unclosed opening tags. Impact ====== A remote attacker can exploit inefficient HTML tag parsing in Django’s strip_tags() function to cause excessive CPU usage, leading to a denial of service. This may affect applications that use the striptags template filter to sanitize user-controlled input, making them vulnerable to slowdown or unresponsiveness when handling specially crafted HTML content.

Arch Linux Security Advisory ASA-202505-9 ========================================= Severity: Medium Date : 2025-05-19 CVE-ID : CVE-2025-47203 Package : dropbear Type : arbitrary command execution Remote : Yes Link : https://security.archlinux.org/AVG-2874 Summary ======= The package dropbear before version 2025.88-1 is vulnerable to arbitrary command execution. Resolution ========== Upgrade to 2025.88-1. # pacman -Syu "dropbear>=2025.88-1" The problem has been fixed upstream in version 2025.88. Workaround ========== None. Description =========== dbclient in Dropbear SSH before 2025.88 allows command injection via an untrusted hostname argument, because a shell is used. Impact ====== A remote attacker can craft a malicious hostname to execute arbitrary commands on a system using dbclient if the hostname is passed without proper sanitization.

[ASA-202505-8] nodejs-lts-iron: multiple issues
by Andrea Denisse 20 May '25

20 May '25

Arch Linux Security Advisory ASA-202505-8 ========================================= Severity: High Date : 2025-05-18 CVE-ID : CVE-2025-23165 CVE-2025-23166 CVE-2025-23167 Package : nodejs-lts-iron Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-2873 Summary ======= The package nodejs-lts-iron before version 20.19.2-1 is vulnerable to multiple issues including denial of service and access restriction bypass. Resolution ========== Upgrade to 20.19.2-1. # pacman -Syu "nodejs-lts-iron>=20.19.2-1" The problems have been fixed upstream in version 20.19.2. Workaround ========== None. Description =========== - CVE-2025-23165 (denial of service) Corrupted pointer in node::fs::ReadFileUtf8(const FunctionCallbackInfo<Value>& args) when args[0] is a string. In Node.js, the ReadFileUtf8 internal binding leaks memory due to a corrupted pointer in uv_fs_s.file: a UTF-16 path buffer is allocated but subsequently overwritten when the file descriptor is set. This results in an unrecoverable memory leak on every call. Repeated use can cause unbounded memory growth, leading to a denial of service. - CVE-2025-23166 (denial of service) Improper error handling in async cryptographic operations crashes process. The C++ method SignTraits::DeriveBits() may incorrectly call ThrowException() based on user-supplied inputs when executing in a background thread, crashing the Node.js process. Such cryptographic operations are commonly applied to untrusted inputs. Thus, this mechanism potentially allows an adversary to remotely crash a Node.js runtime. - CVE-2025-23167 (access restriction bypass) A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using \r\n\rX instead of the required \r\n\r\n. This inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests. The issue was resolved by upgrading llhttp to version 9, which enforces correct header termination. Impact ====== A remote attacker can exploit multiple vulnerabilities in Node.js to cause a denial of service or bypass access restrictions. Improper error handling and memory management flaws may crash the process or lead to unbounded memory usage, while an HTTP parsing inconsistency in Node.js 20.x can enable request smuggling, allowing attackers to evade proxy- based access controls and submit unauthorized requests.
