CVE-2021-40391 3 Debian, Fedoraproject, Gerbv Project 3 Debian Linux, Fedora, Gerbv 2023-11-07 7.5 HIGH 9.8 CRITICAL
An out-of-bounds write vulnerability exists in the drill format T-code tool number functionality of Gerbv 2.7.0, dev (commit b5f1eacd), and the forked version of Gerbv (commit 71493260). A specially-crafted drill file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-40346 3 Debian, Fedoraproject, Haproxy 3 Debian Linux, Fedora, Haproxy 2023-11-07 5.0 MEDIUM 7.5 HIGH
An integer overflow exists in HAProxy 2.0 through 2.5 in htx_add_header that can be exploited to perform an HTTP request smuggling attack, allowing an attacker to bypass all configured http-request HAProxy ACLs and possibly other ACLs.
CVE-2021-40153 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2023-11-07 5.8 MEDIUM 8.1 HIGH
squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination.
CVE-2021-3984 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2023-11-07 6.8 MEDIUM 7.8 HIGH
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3974 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2023-11-07 6.8 MEDIUM 7.8 HIGH
vim is vulnerable to Use After Free
CVE-2021-3973 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2023-11-07 9.3 HIGH 7.8 HIGH
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3941 4 Debian, Fedoraproject, Openexr and 1 more 4 Debian Linux, Fedora, Openexr and 1 more 2023-11-07 2.1 LOW 6.5 MEDIUM
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR.
CVE-2021-3935 4 Debian, Fedoraproject, Pgbouncer and 1 more 4 Debian Linux, Fedora, Pgbouncer and 1 more 2023-11-07 5.1 MEDIUM 8.1 HIGH
When PgBouncer is configured to use "cert" authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of TLS certificate verification and encryption. This flaw affects PgBouncer versions prior to 1.16.1.
CVE-2021-3933 3 Debian, Fedoraproject, Openexr 3 Debian Linux, Fedora, Openexr 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits. This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with application stability or lead to other attack paths.
CVE-2021-3928 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2023-11-07 4.6 MEDIUM 7.8 HIGH
vim is vulnerable to Use of Uninitialized Variable

CVE-2021-3759 2 Debian, Linux 2 Debian Linux, Linux Kernel 2023-11-07 N/A 5.5 MEDIUM
A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2021-3735 2 Debian, Qemu 2 Debian Linux, Qemu 2023-11-07 N/A 4.4 MEDIUM
A deadlock issue was found in the AHCI controller device of QEMU. It occurs on a software reset (ahci_reset_port) while handling a host-to-device Register FIS (Frame Information Structure) packet from the guest. A privileged user inside the guest could use this flaw to hang the QEMU process on the host, resulting in a denial of service condition. The highest threat from this vulnerability is to system availability.
CVE-2021-3712 7 Debian, Mcafee, Netapp and 4 more 32 Debian Linux, Epolicy Orchestrator, Clustered Data Ontap and 29 more 2023-11-07 5.8 MEDIUM 7.4 HIGH
ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not a strict requirement, ASN.1 strings that are parsed using OpenSSL's own "d2i" functions (and other similar parsing functions) as well as any string whose value has been set with the ASN1_STRING_set() function will additionally NUL terminate the byte array in the ASN1_STRING structure. However, it is possible for applications to directly construct valid ASN1_STRING structures which do not NUL terminate the byte array by directly setting the "data" and "length" fields in the ASN1_STRING array. This can also happen by using the ASN1_STRING_set0() function. Numerous OpenSSL functions that print ASN.1 data have been found to assume that the ASN1_STRING byte array will be NUL terminated, even though this is not guaranteed for strings that have been directly constructed. Where an application requests an ASN.1 structure to be printed, and where that ASN.1 structure contains ASN1_STRINGs that have been directly constructed by the application without NUL terminating the "data" field, then a read buffer overrun can occur. The same thing can also occur during name constraints processing of certificates (for example if a certificate has been directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the certificate contains non NUL terminated ASN1_STRING structures). It can also occur in the X509_get1_email(), X509_REQ_get1_email() and X509_get1_ocsp() functions. If a malicious actor can cause an application to directly construct an ASN1_STRING and then process it through one of the affected OpenSSL functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack). It could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext). Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k). Fixed in OpenSSL 1.0.2za (Affected 1.0.2-1.0.2y).
CVE-2021-3711 5 Debian, Netapp, Openssl and 2 more 31 Debian Linux, Active Iq Unified Manager, Clustered Data Ontap and 28 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen" parameter is populated with the buffer size required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the "out" parameter. A bug in the implementation of the SM2 decryption code means that the calculation of the buffer size required to hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size required by the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the application a second time with a buffer that is too small. A malicious attacker who is able present SM2 content for decryption to an application could cause attacker chosen data to overflow the buffer by up to a maximum of 62 bytes altering the contents of other data held after the buffer, possibly changing application behaviour or causing the application to crash. The location of the buffer is application dependent but is typically heap allocated. Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k).
CVE-2021-3671 3 Debian, Netapp, Samba 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.
