Vulnerabilities

CVE-2024-12084 is a critical (CVSS 9.8) heap-based buffer overflow in the rsync daemon, caused by improper handling of an attacker-controlled checksum length (s2length): when MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH of 16 bytes, a connecting peer can cause an out-of-bounds write into the fixed-size sum2 buffer. A remote attacker who can reach the rsync daemon needs no privileges or user interaction to trigger the flaw, and the resulting heap corruption can lead to remote code execution on the server (as demonstrated in the referenced Google security research) or crash the daemon. Any system running a vulnerable rsync daemon is affected — including rsync shipped with Red Hat Enterprise Linux, SUSE Linux, AlmaLinux, Arch Linux, Gentoo, NixOS and SmartOS — with the highest risk on servers where the daemon is exposed on TCP port 873. No confirmed in-the-wild exploitation is documented yet (the CVE is not on CISA KEV), but a public proof-of-concept exists from Google Cloud researchers and EPSS assigns a 72.1% probability of exploitation within 30 days, indicating high imminent risk.

Do: Upgrade rsync to 3.4.1 or later, or install the patched rsync package from your distribution (Red Hat, SUSE, AlmaLinux, Arch, Gentoo, NixOS and SmartOS have all shipped fixes). Until patched, restrict TCP port 873 to trusted networks or disable the rsync daemon where it is not needed. Audit hosts for listening rsync daemons and verify the installed rsync version against your vendor's advisory.

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

The Widget Settings Importer/Exporter Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the wp_ajax_import_widget_dataparameter AJAX action in versions up to, and including, 1.5.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with subscriber-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

An authenticated server-side request forgery in Nextcloud server 16.0.1 allowed to detect local and remote services when adding a new subscription in the calendar application.

As part of a winning Pwn2Own entry, a researcher demonstrated a sandbox escape by installing a malicious language pack and then opening a browser feature that used the compromised translation. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.

libavcodec/hevcdec.c in FFmpeg 3.4 and 4.1.2 mishandles detection of duplicate first slices, which allows remote attackers to cause a denial of service (NULL pointer dereference and out-of-array access) or possibly have unspecified other impact via crafted HEVC data.

The LDAP backend in Novell eDirectory before 9.0 SP4 when switched to EBA (Enhanced Background Authentication) kept open connections without EBA.

Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request.

The mkdumprd script called "dracut" in the current working directory "." allows local users to trick the administrator into executing code as root.

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries.

glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.

game-music-emu before 0.6.1 mishandles unspecified integer values.

Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the get_user function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL.

Novell iManager 2.7.x before 2.7 SP7 Patch 10 HF1 and NetIQ iManager 3.x before 3.0.3.1 have a webshell upload vulnerability.

Novell iManager 2.7 before SP7 Patch 9, NetIQ iManager 3.x before 3.0.2.1, Novell eDirectory 8.8.x before 8.8 SP8 Patch 9 Hotfix 2, and NetIQ eDirectory 9.x before 9.0.2 Hotfix 2 (9.0.2.2) use the deprecated MD5 hashing algorithm in a communications certificate.

Integer overflow in the Post Office Agent in Novell GroupWise before 2014 R2 Service Pack 1 Hot Patch 1 might allow remote attackers to execute arbitrary code via a long (1) username or (2) password, which triggers a heap-based buffer overflow.

A reflected XSS vulnerability exists in the web console of the Document Viewer Agent in Novell GroupWise before 2014 R2 Support Pack 1 Hot Patch 2 that may enable a remote attacker to execute JavaScript in the context of a valid user's browser session by getting the user to click on a specially crafted link. This could lead to session compromise or other browser-based attacks.
