FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. This issue affects Clients only. Integer underflow leading to DOS (e.g. abort due to `WINPR_ASSERT` with default compilation flags). When an insufficient blockLen is provided, and proper length validation is not performed, an Integer Underflow occurs, leading to a Denial of Service (DOS) vulnerability. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.

DHCP Server Service Denial of Service Vulnerability

An integer underflow was discovered in Fort 1.6.3 and 1.6.4 before 1.6.5. A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) a Manifest RPKI object containing an empty fileList. Fort dereferences (and, shortly afterwards, writes to) this array during a shuffle attempt, before the validation that would normally reject it when empty. This out-of-bounds access is caused by an integer underflow that causes the surrounding loop to iterate infinitely. Because the product is permanently stuck attempting to overshuffle an array that doesn't actually exist, a crash is nearly guaranteed.

An issue was discovered in dec_patch_dictionary.cc in libjxl before 0.8.2. An integer underflow in patch decoding can lead to a denial of service, such as an infinite loop.

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in qtdemux_parse_trak function within qtdemux.c. During the strf parsing case, the subtraction size -= 40 can lead to a negative integer overflow if it is less than 40. If this happens, the subsequent call to gst_buffer_fill will invoke memcpy with a large tocopy size, resulting in an OOB-read. This vulnerability is fixed in 1.24.10.

A vulnerability has been identified in Capital Embedded AR Classic 431-422 (All versions), Capital Embedded AR Classic R20-11 (All versions < V2303), PLUSCONTROL 1st Gen (All versions), SIMOTICS CONNECT 400 (All versions < V0.5.0.0). Malformed TCP packets with a corrupted SACK option leads to Information Leaks and Denial-of-Service conditions. (FSMD-2021-0015)

Integer underflow in pppd in cbcp.c for ppp 2.4.1 allows remote attackers to cause a denial of service (daemon crash) via a CBCP packet with an invalid length value that causes pppd to access an incorrect memory location.

There is an Integer Underflow (Wrap or Wraparound) Vulnerability in Huawei Smartphone.Successful exploitation of this vulnerability may cause DoS of Samgr.
