Integer Overflow or Wraparound

There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME. Fixed in OpenSSL 1.1.1e (Affected 1.1.1-1.1.1d). Fixed in OpenSSL 1.0.2u (Affected 1.0.2-1.0.2t).Show less

In radare2 through 4.0, there is an integer overflow for the variable new_token_size in the function r_asm_massemble at libr/asm/asm.c. This integer overflow will result in a Use-After-Free for the buffer tokens, which can be filled with arbitrary malicious data after the free. This allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted input.Show less

Hardlink before 0.1.2 has multiple integer overflows leading to heap-based buffer overflows because of the way string lengths concatenation is done in the calculation of the required memory space to be used. A remote attacker could provide a specially-crafted directory tree and trick the local user into consolidating it, leading to hardlink executable crash or potentially arbitrary code execution with user privileges.Show less

The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.Show less

An exploitable integer overflow vulnerability exists in the flattenIncrementally function in the xcf2png and xcf2pnm binaries of xcftools 1.0.7. An integer overflow can occur while calculating the row's allocation size, that could be exploited to corrupt memory and eventually execute arbitrary code. In order to trigger this vulnerability, a victim would need to open a specially crafted XCF file.Show less

An exploitable integer overflow vulnerability exists in the flattenIncrementally function in the xcf2png and xcf2pnm binaries of xcftools, version 1.0.7. An integer overflow can occur while walking through tiles that could be exploited to corrupt memory and execute arbitrary code. In order to trigger this vulnerability, a victim would need to open a specially crafted XCF file.Show less

Buffer overflow can occur while processing non-standard NAN message from user space. in Snapdragon Auto, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wired Infrastructure and Networking in APQ8009, APQ8017, APQ8053, APQ8064, APQ8096AU, IPQ4019, IPQ8064, IPQ8074, MDM9206, MDM9207C, MDM9607, MDM9640, MDM9650, MSM8905, MSM8996AU, QCA6174A, QCA6574AU, QCA9377, QCA9379, QCN7605, QCS405, QCS605, SDA660, SDA845, SDM636, SDM660, SDM845, SDX20, SDX24, SM8150Show less

Integer overflow to buffer overflow vulnerability in PostScript image handling code used by the PostScript- and PDF-compatible interpreters due to incorrect buffer size calculation. in PostScript and PDF printers that use IPS versions prior to 2019.2 in PostScript and PDF printers that use IPS versions prior to 2019.2Show less

An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression.Show less

P30 smart phones with versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1) have an integer overflow vulnerability due to insufficient check on specific parameters. An attacker tricks the user into installing a malicious application, obtains the root permission and constructs specific parameters to the camera program to exploit this vulnerability. Successful exploit could cause the program to break down or allow for arbitrary code execution.Show less

An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.Show less

An exploitable integer overflow vulnerability exists in the BMP header parsing functionality of LEADTOOLS 20. A specially crafted BMP image file can cause an integer overflow, potentially resulting in code execution. An attacker can specially craft a BMP image to trigger this vulnerability.Show less
