WECON Technology Co., Ltd. PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior have a stack-based buffer overflow vulnerability which may allow remote code execution.

Advantech WebAccess 8.3.1 and earlier has several stack-based buffer overflow vulnerabilities that have been identified, which may allow an attacker to execute arbitrary code.

Fuji Electric V-Server 4.0.3.0 and prior, Several out-of-bounds write vulnerabilities have been identified, which may allow remote code execution.

Fuji Electric V-Server 4.0.3.0 and prior, A heap-based buffer overflow vulnerability has been identified, which may allow remote code execution.

WECON Technology Co., Ltd. PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior parse files and pass invalidated user data to an unsafe method call, which may allow code to be executed in the context of an administrator.

A stack-based buffer overflow vulnerability in Opto 22 PAC Control Basic and PAC Control Professional versions R10.0a and prior may allow remote code execution.

A buffer overflow issue was discovered in the Yubico-Piv 1.5.0 smartcard driver. The file lib/ykpiv.c contains the following code in the function `ykpiv_transfer_data()`: {% highlight c %} if(*out_len + recv_len - 2 > max_out) { fprintf(stderr, "Output buffer to small, wanted to write %lu, max was %lu.", *out_len + recv_len - 2, max_out); } if(out_data) { memcpy(out_data, data, recv_len - 2); out_data += recv_len - 2; *out_len += recv_len - 2; } {% endhighlight %} -- it is clearly checked whether the buffer is big enough to hold the data copied using `memcpy()`, but no error handling happens to avoid the `memcpy()` in such cases. This code path can be triggered with malicious data coming from a smartcard.

Pydio 4.2.1 through 8.2.1 has an authenticated remote code execution vulnerability in which an attacker with administrator access to the web application can execute arbitrary code on the underlying system via Command Injection.

System command injection in the /DroboPix/api/drobopix/demo endpoint on Drobo 5N2 NAS version 4.0.5-13.28.96115 allows unauthenticated attackers to execute system commands via the payload in a POST request.

System command injection in the /DroboAccess/delete_user endpoint in Drobo 5N2 NAS version 4.0.5-13.28.96115 allows unauthenticated attackers to execute system commands via the "username" URL parameter.

System command injection in the /DroboAccess/enable_user endpoint in Drobo 5N2 NAS version 4.0.5-13.28.96115 allows unauthenticated attackers to execute system commands via the "username" URL parameter.

libmspack: out-of-bounds write in kwajd_read_headers in mspack/kwajd.c

An issue was discovered in kwajd_read_headers in mspack/kwajd.c in libmspack before 0.7alpha. Bad KWAJ file header extensions could cause a one or two byte overwrite.

glusterfs: Heap-based buffer overflow via "gf_getspec_req" RPC message

The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflow in the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact.

kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi target

A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.

atomic-openshift: oc patch with json causes masterapi service crash

An out of bound write can occur when patching an Openshift object using the 'oc patch' functionality in OpenShift Container Platform before 3.7. An attacker can use this flaw to cause a denial of service attack on the Openshift master api service which provides cluster management.

kernel: Out-of-bounds access in write_extent_buffer() when mounting and operating a crafted btrfs image

An issue was discovered in the Linux kernel through 4.17.10. There is out-of-bounds access in write_extent_buffer() when mounting and operating a crafted btrfs image, because of a lack of verification that each block group has a corresponding chunk at mount time, within btrfs_read_block_groups in fs/btrfs/extent-tree.c.

libX11: Out of Bounds write in XListExtensions in ListExt.c

An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading to DoS or remote code execution.

libX11: Off-by-one error in XListExtensions in ListExt.c

An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other impact.

In conference-scheduler-cli, a pickle.load call on imported data allows remote attackers to execute arbitrary code via a crafted .pickle file, as demonstrated by Python code that contains an os.system call.

ImageMagick: Uninitialized variable in coders/mat.c:ReadMATImageV4() allows for memory corruption

The ReadMATImageV4 function in coders/mat.c in ImageMagick 7.0.8-7 uses an uninitialized variable, leading to memory corruption.
