CVE-2026-15534——
———Perl versions through 5.45.1 have out-of-bounds heap reads and writes during regular expression matching via an undersized superlinear cache in S_regmatch.
The regex engine's superlinear cache holds one bit per subject position for each participating WHILEM node, so the bit count is the subject length plus one times the number of nodes. Nothing checks that product for positive overflow of the signed 32-bit count: a 286331153 byte subject matched against a pattern with 15 participating nodes stores the count as 14, leaving a two byte cache. The cache is then indexed from the real match position and node number, so reads go past the end of the allocation, and on failure CACHEsayNO sets a bit past it.
A caller that matches an attacker controlled subject of this size against a pattern of this shape can crash the process or corrupt heap memory.3hCVE-2026-54212—38.0%
——11Tobit Laboratories AG TeamDavid's Webbox application implements an API endpoint that is vulnerable to a
buffer overflow condition. By submitting a specially crafted JSON body,
such as one that is at least 8 characters long and begins with a number,
an unauthenticated attacker can cause the server to crash, resulting in
denial of service. Depending on the stack state or if a stack canary
can be disclosed through another vulnerability, this buffer overflow
could potentially lead to remote code execution and full compromise of
the server. This issue affects TeamDavid through Rollout 524.2dCVE-2026-54211—33.7%
——10Tobit Laboratories AG TeamDavid's Webbox application’s endpoint “//serverClient_close.html” is vulnerable to a
buffer overflow vulnerability in multiple form data parameters. By
submitting excessively long values in these parameters, an authenticated
attacker can trigger a server crash, resulting in denial of service.
Depending on the stack state or if a stack canary can be disclosed
through another vulnerability, this buffer overflow could potentially be
exploited for remote code execution, leading to full compromise of the
server. This issue affects TeamDavid through Rollout 524.2dCVE-2026-54210—38.0%
——11Tobit Laboratories AG TeamDavid's Webbox application implements various file upload functionalities that are
vulnerable to a buffer overflow condition. By specifying an excessively
long filename in a file upload request, an unauthenticated attacker can
trigger a crash of the server, resulting in a denial of service.
Depending on the stack state or if a stack canary can be disclosed
through another vulnerability, this buffer overflow could potentially be
exploited for remote code execution, leading to full compromise of the
server. This issue affects TeamDavid through Rollout 524.2dCVE-2026-172644.3 MED20.9%
——6Opening a crafted DICOM file containing malicious JPEG-compressed pixel data triggers an attacker-controlled heap out-of-bounds write, which may allow an attacker to remotely execute arbitrary code.2dCVE-2026-83257.8 HIG2.7%
——1A maliciously crafted PDF file, when parsed through Autodesk Revit, can force an Out-of-Bounds Write vulnerability. A malicious actor may leverage this vulnerability to cause a crash, cause data corruption, or execute arbitrary code in the context of the current process.2d
