kernel: out-of-bounds access in function hclge_tm_schd_mode_vnet_base_cfg

An issue was discovered in the Linux kernel before 5.2.3. An out of bounds access exists in the function hclge_tm_schd_mode_vnet_base_cfg in the file drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.

kernel: out-of-bounds read in fs/cifs/smb2pdu.c

An issue was discovered in the Linux kernel before 5.0.10. SMB2_negotiate in fs/cifs/smb2pdu.c has an out-of-bounds read because data structures are incompletely updated after a change from smb30 to smb21.

Secure Reliable Transport (SRT) through 1.3.4 has a CSndUList array overflow if there are many SRT connections.

An issue was discovered in app-layer-ssl.c in Suricata 4.1.4. Upon receiving a corrupted SSLv3 (TLS 1.2) packet, the parser function TLSDecodeHSHelloExtensions tries to access a memory region that is not allocated, because the expected length of HSHelloExtensions does not match the real length of the HSHelloExtensions part of the packet.

tigervnc: Stack buffer overflow in CMsgReader::readSetCursor

TigerVNC version prior to 1.10.1 is vulnerable to stack buffer overflow, which could be triggered from CMsgReader::readSetCursor. This vulnerability occurs due to insufficient sanitization of PixelFormat. Since remote attacker can choose offset from start of the buffer to start writing his values, exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.

tigervnc: Heap buffer overflow in DecodeManager::decodeRect

TigerVNC version prior to 1.10.1 is vulnerable to heap buffer overflow, which could be triggered from DecodeManager::decodeRect. Vulnerability occurs due to the signdness error in processing MemOutStream. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.

tigervnc: Heap buffer overflow in TightDecoder::FilterGradient

TigerVNC version prior to 1.10.1 is vulnerable to heap buffer overflow, which occurs in TightDecoder::FilterGradient. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.

tigervnc: Heap buffer overflow triggered from CopyRectDecoder due to incorrect value checks

TigerVNC version prior to 1.10.1 is vulnerable to heap buffer overflow. Vulnerability could be triggered from CopyRectDecoder due to incorrect value checks. Exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity.

TurboVNC server code contains stack buffer overflow vulnerability in commit prior to cea98166008301e614e0d36776bf9435a536136e. This could possibly result into remote code execution, since stack frame is not protected with stack canary. This attack appear to be exploitable via network connectivity. To exploit this vulnerability authorization on server is required. These issues have been fixed in commit cea98166008301e614e0d36776bf9435a536136e.

rdesktop: multiple out-of-bound access read vulnerabilities

RDesktop version 1.8.4 contains multiple out-of-bound access read vulnerabilities in its code, which results in a denial of service (DoS) condition. This attack appear to be exploitable via network connectivity. These issues have been fixed in version 1.8.5

TightVNC code version 1.3.10 contains heap buffer overflow in InitialiseRFBConnection function, which can potentially result code execution. This attack appear to be exploitable via network connectivity.

TightVNC code version 1.3.10 contains heap buffer overflow in rfbServerCutText handler, which can potentially result code execution.. This attack appear to be exploitable via network connectivity.

kernel: out-of-bounds array access in __xfrm_policy_unlink

An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation.

An issue was discovered in Rivet Killer Control Center before 2.1.1352. IOCTL 0x120404 in KfeCo10X64.sys fails to validate an offset passed as a parameter during a memory operation, leading to an out-of-bounds read that can be used as part of a chain to escalate privileges (issue 2 of 2).

An issue was discovered in Rivet Killer Control Center before 2.1.1352. IOCTL 0x120404 in KfeCo10X64.sys fails to validate an offset passed as a parameter during a memory operation, leading to an out-of-bounds read that can be used as part of a chain to escalate privileges (issue 1 of 2).

An issue was discovered in Rivet Killer Control Center before 2.1.1352. IOCTL 0x120444 in KfeCo10X64.sys fails to validate an offset passed as a parameter during a memory operation, leading to an arbitrary read primitive that can be used as part of a chain to escalate privileges.

wolfSSL 4.1.0 has a one-byte heap-based buffer over-read in DecodeCertExtensions in wolfcrypt/src/asn.c because reading the ASN_BOOLEAN byte is mishandled for a crafted DER certificate in GetLength_ex.

An issue was discovered in the simd-json crate before 0.1.15 for Rust. There is an out-of-bounds read and an incorrect crossing of a page boundary.

GNU Libextractor through 1.9 has a heap-based buffer over-read in the function EXTRACTOR_dvi_extract_method in plugins/dvi_extractor.c.

kernel: out of bounds read in drivers/media/usb/dvb-usb/technisat-usb2.c

drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir).
