CVE-2021-29157 2 Dovecot, Fedoraproject 2 Dovecot, Fedora 2024-11-21 2.1 LOW 7.5 HIGH
Dovecot before 2.3.15 allows ../ Path Traversal. An attacker with access to the local filesystem can trick OAuth2 authentication into using an HS256 validation key from an attacker-controlled location. This occurs during use of local JWT validation with the posix fs driver.
CVE-2021-29155 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer arithmetic operations, the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations.
CVE-2021-29154 4 Debian, Fedoraproject, Linux and 1 more 20 Debian Linux, Fedora, Linux Kernel and 17 more 2024-11-21 7.2 HIGH 7.8 HIGH
BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c.
CVE-2021-29063 2 Fedoraproject, Mpmath 2 Fedora, Mpmath 2024-11-21 5.0 MEDIUM 7.5 HIGH
A Regular Expression Denial of Service (ReDOS) vulnerability was discovered in Mpmath v1.0.0 through v1.2.1 when the mpmathify function is called.
CVE-2021-28972 3 Fedoraproject, Linux, Netapp 5 Fedora, Linux Kernel, Cloud Backup and 2 more 2024-11-21 7.2 HIGH 6.7 MEDIUM
In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and remove_slot_store mishandle drc_name '\0' termination, aka CID-cc7a0bb058b8.
CVE-2021-28971 4 Debian, Fedoraproject, Linux and 1 more 9 Debian Linux, Fedora, Linux Kernel and 6 more 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS status in a PEBS record is mishandled, aka CID-d88d05a9e0b6.
CVE-2021-28965 2 Fedoraproject, Ruby-lang 3 Fedora, Rexml, Ruby 2024-11-21 5.0 MEDIUM 7.5 HIGH
The REXML gem before 3.2.5 in Ruby before 2.6.7, 2.7.x before 2.7.3, and 3.x before 3.0.1 does not properly address XML round-trip issues. An incorrect document can be produced after parsing and serializing.
CVE-2021-28964 4 Debian, Fedoraproject, Linux and 1 more 9 Debian Linux, Fedora, Linux Kernel and 6 more 2024-11-21 1.9 LOW 4.7 MEDIUM
A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc.
CVE-2021-28957 5 Debian, Fedoraproject, Lxml and 2 more 5 Debian Linux, Fedora, Lxml and 2 more 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
An XSS vulnerability was discovered in python-lxml's clean module versions before 4.6.3. When disabling the safe_attrs_only and forms arguments, the Cleaner class does not remove the formaction attribute allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS code on users who interact with incorrectly sanitized HTML. This issue is patched in lxml 4.6.3.
CVE-2021-28952 3 Fedoraproject, Linux, Netapp 11 Fedora, Linux Kernel, A250 and 8 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
An issue was discovered in the Linux kernel through 5.11.8. The sound/soc/qcom/sdm845.c soundwire device driver has a buffer overflow when an unexpected port ID number is encountered, aka CID-1c668e1c0a0f. (This has been fixed in 5.12-rc4.)
CVE-2021-28951 3 Fedoraproject, Linux, Netapp 11 Fedora, Linux Kernel, A250 and 8 more 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in fs/io_uring.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (deadlock) because exit may be waiting to park a SQPOLL thread, but concurrently that SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25.
CVE-2021-28950 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A "stall on CPU" can occur because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1.
CVE-2021-28879 2 Fedoraproject, Rust-lang 2 Fedora, Rust 2024-11-21 7.5 HIGH 9.8 CRITICAL
In the standard library in Rust before 1.52.0, the Zip implementation can report an incorrect size due to an integer overflow. This bug can lead to a buffer overflow when a consumed Zip iterator is used again.
CVE-2021-28878 2 Fedoraproject, Rust-lang 2 Fedora, Rust 2024-11-21 4.3 MEDIUM 7.5 HIGH
In the standard library in Rust before 1.52.0, the Zip implementation calls __iterator_get_unchecked() more than once for the same index (under certain conditions) when next_back() and next() are used together. This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.
CVE-2021-28876 2 Fedoraproject, Rust-lang 2 Fedora, Rust 2024-11-21 4.3 MEDIUM 5.3 MEDIUM
In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls __iterator_get_unchecked() more than once for the same index when the underlying iterator panics (in certain conditions). This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.
CVE-2021-28861 2 Fedoraproject, Python 2 Fedora, Python 2024-11-21 N/A 7.4 HIGH
Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states "Warning: http.server is not recommended for production. It only implements basic security checks."
CVE-2021-28834 3 Debian, Fedoraproject, Kramdown Project 3 Debian Linux, Fedora, Kramdown 2024-11-21 6.8 MEDIUM 9.8 CRITICAL
Kramdown before 2.3.1 does not restrict Rouge formatters to the Rouge::Formatters namespace, and thus arbitrary classes can be instantiated.
CVE-2021-28831 3 Busybox, Debian, Fedoraproject 3 Busybox, Debian Linux, Fedora 2024-11-21 5.0 MEDIUM 7.5 HIGH
decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer, with a resultant invalid free or segmentation fault, via malformed gzip data.
CVE-2021-28710 2 Fedoraproject, Xen 2 Fedora, Xen 2024-11-21 6.9 MEDIUM 8.8 HIGH
certain VT-d IOMMUs may not work in shared page table mode For efficiency reasons, address translation control structures (page tables) may (and, on suitable hardware, by default will) be shared between CPUs, for second-level translation (EPT), and IOMMUs. These page tables are presently set up to always be 4 levels deep. However, an IOMMU may require the use of just 3 page table levels. In such a configuration the lop level table needs to be stripped before inserting the root table's address into the hardware pagetable base register. When sharing page tables, Xen erroneously skipped this stripping. Consequently, the guest is able to write to leaf page table entries.
CVE-2021-28709 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-11-21 6.9 MEDIUM 7.8 HIGH
issues with partially successful P2M updates on x86 T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). In some cases the hypervisor carries out the requests by splitting them into smaller chunks. Error handling in certain PoD cases has been insufficient in that in particular partial success of some operations was not properly accounted for. There are two code paths affected - page removal (CVE-2021-28705) and insertion of new pages (CVE-2021-28709). (We provide one patch which combines the fix to both issues.)
