Weekly CVE digest
One email a week with newly published vulnerabilities worth knowing about. No account needed.
This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.
In the Linux kernel, in the L2TP subsystem, a possible tunnel refcount underflow was fixed, which could occur during session deletion when the tunnel pointer was invalid.
In the Linux kernel, in the Btrfs filesystem, an issue with readahead on the relocation inode was fixed when the filesystem uses a RAID stripe tree (RST), which could cause ENOENT errors.
In the Linux kernel, a vulnerability was found in the F2FS filesystem involving uninitialized value access in the f2fs_sanity_check_node_footer function. The issue was reported by syzbot and may lead to unpredictable system behavior.
A use-after-free vulnerability in SEV firmware allows a malicious hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent, potentially leading to loss of integrity.
In the Linux kernel, a vulnerability in the mshv_vtl component occurs when registering VTL0 memory via MSHV_ADD_VTL0_MEMORY, where the computed vmemmap_shift may exceed MAX_FOLIO_ORDER, leading to incorrect behavior.
In the Linux kernel, in the sc16is7xx serial driver, a TX FIFO corruption was fixed that could occur when a packet was received on channel A at almost the same time as a packet was about to be transmitted on channel B.
A vulnerability in the Linux kernel's FUSE filesystem causes a hang during sync initialization when the FUSE server exits (e.g., due to error or crash) while processing the FUSE_INIT request. The issue stems from the lack of abort on a fatal signal, blocking filesystem creation.
The curl_url_get() function in libcurl offers punycode conversions to and from IDN. When converting a name that is exactly 256 bytes, libcurl reads outside a stack-based buffer when built with the macidn IDN backend.
A vulnerability in SEV (Secure Encrypted Virtualization) firmware allows a privileged attacker to modify the lock bit, potentially downgrading the firmware and compromising system integrity.
A vulnerability in Linux PAM before version 1.6.0 allows attackers to cause a denial of service by blocking the login process. The issue stems from the lack of the O_DIRECTORY flag in the openat call for the protect_dir function, enabling the use of mkfifo.
In the Linux kernel, a vulnerability was found in the SMB client related to directory separator handling in SMB1 UNIX mounts. The issue occurs when @cifs_sb->mnt_cifs_flags is read or updated before calling reset_cifs_unix_caps(), potentially causing incorrect behavior.
A vulnerability in the UEFI implementation within QEMU (or similar software) causes a heap overflow in the hardware module (hw/uefi). An attacker can exploit this flaw to gain unauthorized access or execute arbitrary code.
A vulnerability in the Mail library affects the q_value_decode and b_value_decode functions, which decode only the first RFC 2047 encoded-word in a string and use an overly greedy pattern to match the charset token. A crafted, malformed encoded-word embedded in an address display name or local part could cause incorrect decoding.
Insufficient granularity of access control in SEV firmware allows a privileged user with a malicious hypervisor to create a SEV-ES guest with an ASID meant for SEV-SNP guests, potentially leading to partial loss of confidentiality.
A vulnerability in the Nokogiri library affects the `Nokogiri::XML::NodeSet#[]` method (and its alias `#slice`). The index check against the node set's bounds used a 32-bit-truncated copy of the index, allowing a large negative index to pass the check and then be used at full width, reading outside the node set's storage.
A NULL pointer dereference vulnerability was found in the Linux kernel's ALSA driver for the TASCAM US-144MKII device. A malicious USB device can have a configuration with interface number 1 but missing interface 0, leading to a system crash.
CoreDNS before version 1.14.0 has a vulnerability in gRPC, HTTPS, and HTTP/3 server implementations that lack critical resource-limiting controls. An unauthenticated remote attacker can exhaust memory and degrade or crash the server by opening many concurrent connections.
An issue in Axios 1.5.1 inadvertently reveals the confidential XSRF-TOKEN stored in cookies by including it in the HTTP header X-XSRF-TOKEN for every request made to any host, allowing attackers to view sensitive information.
A flaw was found in systemd where uncontrolled recursion in systemd-tmpfiles may lead to a denial of service at boot time when too many nested directories are created in /tmp.
A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could use this issue to install a different revision on a repository, threatening data integrity. The issue is fixed in version 21.1.
