CVE-2026-58102

Summary of CVE-2026-58102 : Crypt::OpenSSL::X509 (Perl) versions before 2.1.3 are affected by a heap out-of-bounds read when processing long certificate extension OIDs in hv_exts. The vulnerability arises while building the extension hash through extensions(), extensions_by_long_name(), extension...

CVE-2026-51536

In OpENer 2.3.0 commit 76b95cf when parsing incoming CIP Common Industrial Protocol network packets, the length parameter is inconsistently typed across the call stack. Specifically, an upstream length calculated as an int is passed to a downstream function that expects an EipInt16 a 16-bit signe...

OpenEXR: OpenEXR: Information disclosure and denial of service via malformed EXR files

A flaw was found in OpenEXR. A remote attacker could exploit a vulnerability in the IDManifest::init function when processing specially crafted EXR files. The function attempts to reconstruct strings from a prefix-compressed representation. If a previous string exceeds 255 bytes, the subsequent...

CVE-2026-57432

Perl versions through 5.43.10 have an integer overflow in Smeasurestruct leading to an out-of-bounds heap read in pack and unpack. Smeasurestruct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the...

freerdp: FreeRDP: Out-of-bounds write in planar bitmap decoder allows arbitrary code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The planar bitmap decoder contains an out-of-bounds heap write vulnerability when processing RLE planar data. A remote attacker could exploit this by providing specially crafted RLE planar data, leading to an...

gimp: GIMP: Arbitrary code execution via heap-based buffer overflow in HDR file parsing

A flaw was found in GIMP. This vulnerability, a heap-based buffer overflow, occurs during the parsing of HDR High Dynamic Range files due to insufficient validation of user-supplied data length. A remote attacker could exploit this by convincing a user to open a specially crafted malicious file,...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in font alias resolution due to libXfont2 name length mismatch

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...

CVE-2026-14683

A flaw was found in HdrHistogram. A local attacker can exploit a vulnerability in the decodeFromCompressedByteBuffer function by manipulating the lengthOfCompressedContents argument. This manipulation leads to uncontrolled memory allocation, which can result in a Denial of Service DoS condition,...

PT-2026-60047

Impact read character string and read string in src/zeroconf/ protocol/incoming.py sliced self.dataself.offset : self.offset + length and advanced self.offset by the declared length without checking it against self. data len. Python's slice silently returns fewer bytes when the end index runs pas...

CVE-2026-51536

OpENer 2.3.0 is affected by CVE-2026-51536 due to inconsistent typing of the length parameter across the call stack: an upstream int length is passed to a downstream function expecting a 16-bit signed EipInt16. A crafted CIP packet can cause the length to overflow or become negative, bypassing bo...

CVE-2026-10665

In Zephyr's WireGuard subsystem subsys/net/lib/wireguard, wgprocessdatamessage in wgcrypto.c linearizes an inbound transport-data payload into a fixed pool buffer of CONFIGWIREGUARDBUFLEN bytes before decryption. The call netbuflinearizebuf-data, datalen, pkt-buffer, ..., datalen passed the...

CVE-2026-10666 Stack buffer overflow in `net_ipaddr_parse()` IPv4 address-with-port parsing in `subsys/net/ip/utils.c`

CVE-2026-10665

CVE-2026-10665 concerns Zephyr’s WireGuard implementation (subsys/net/lib/wireguard). The flaw: wg_process_data_message() linearizes an inbound payload into a fixed pool buffer, passing the attacker-controlled data_len as both the destination capacity and copy length to net_buf_linearize, ignorin...
