QEMU: rdma: OOB access when building scatter-gather array

hw/rdma/rdma_backend.c in QEMU allows guest OS users to trigger out-of-bounds access via a PvrdmaSqWqe ring element with a large num_sge value.

haproxy: Out-of-bounds read in dns.c:dns_validate_dns_response() allows for memory disclosure

An out-of-bounds read in dns_validate_dns_response in dns.c was discovered in HAProxy through 1.8.14. Due to a missing check when validating DNS responses, remote attackers might be able read the 16 bytes corresponding to an AAAA record from the non-initialized part of the buffer, possibly accessing anything that was left on the stack, or even past the end of the 8193-byte buffer, depending on the value of accepted_payload_size.

exiv2: Heap-based buffer over-read in Exiv2::Jp2Image::encodeJp2Header resulting in a denial of service

There is a heap-based buffer over-read in Exiv2::Jp2Image::encodeJp2Header of jp2image.cpp in Exiv2 0.27-RC3. A crafted input will lead to a remote denial of service attack.

exiv2: Segmentation fault in Exiv2::Internal::TiffParserWorker::findPrimaryGroups function

There is a SEGV in Exiv2::Internal::TiffParserWorker::findPrimaryGroups of tiffimage_int.cpp in Exiv2 0.27-RC3. A crafted input will lead to a remote denial of service attack.

exiv2: Heap-based buffer over-read in Exiv2::tEXtToDataBuf function resulting in a denial of service

There is a heap-based buffer over-read in the Exiv2::tEXtToDataBuf function of pngimage.cpp in Exiv2 0.27-RC3. A crafted input will lead to a remote denial of service attack.

httpd: Out of bounds read in mod_cache_socache can allow a remote attacker to cause DoS

A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.

httpd: Out of bounds access after failure in reading the HTTP request

A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Foxit Reader 9.0.0.29935. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DataSubBlock structures in GIF images. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-5490.

kernel: Out of bounds read in ext4/balloc.c:ext4_valid_block_bitmap() causes crash with crafted ext4 image

The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers.

corosync: Integer overflow in exec/totemcrypto.c:authenticate_nss_2_3() function

corosync before version 2.4.4 is vulnerable to an integer overflow in exec/totemcrypto.c.

advancecomp: Heap buffer overflow in zip.cc:zip_entry::load_cent() allows for denial of service or unspecified impact via crafted ZIP file

An out-of-bounds heap buffer read flaw was found in the way advancecomp before 2.1-2018/02 handled processing of ZIP files. An attacker could potentially use this flaw to crash the advzip utility by tricking it into processing crafted ZIP files.

389-ds-base: remote Denial of Service (DoS) via search filters in SetUnicodeStringFromUTF_8 in collate.c

An out-of-bounds memory read flaw was found in the way 389-ds-base handled certain LDAP search filters, affecting all versions including 1.4.x. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.

kernel: oob memory read in hso_probe in drivers/net/usb/hso.c

The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allows arbitrary read in the kernel address space.

In YARA 3.8.1, bytecode in a specially crafted compiled rule can read data from any arbitrary address in memory, in libyara/exec.c. Specifically, OP_COUNT can read a DWORD.
