CVE-2026-54538 xrdp: Pre-auth infinite loop via totalLength=0 in TS_SHARECONTROLHEADER

xrdp is an open source RDP server. In versions 0.10.6 and prior, a n issue was discovered where the software fails to properly validate the totalLength field within the RDP protocol control header during packet reception. An unauthenticated remote attacker can exploit this vulnerability by sendin...

PT-2026-61257

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM SEV component where Port I/O requests with a length or count of 0 were not explicitly ignored. This could lead to length underflow when setting up the software...

CVE-2026-53994

ProFTPD mod_sftp has a heap-based buffer overflow reachable by an authenticated SFTP user. The fxp_packet_read() function accepts an attacker-controlled 32-bit big-endian SFTP packet length without minimum sanity checks. A value of 0 underflows in the read path, yielding an oversized request (~4 ...

GoBGP confederation validation panics on empty AS_PATH attribute

Found through variant analysis based on CVE-2026-41643 Summary GoBGP accepts a zero-length ASPATH during UPDATE decoding and later panics while validating that attribute for a confederation eBGP peer. The vulnerable path is in the BGP UPDATE validator: a malformed UPDATE that should be rejected a...

PYSEC-2026-2028 Vyper's `slice()` may elide side-effects when output length is 0

Impact the slice builtin can elide side effects when the output length is 0, and the source bytestring is a builtin msg.data or .code. the reason is that for these source locations, the check that length = 1 is skipped:...
