Integer Overflow or Wraparound

An issue was discovered in MBed OS 6.16.0. During processing of HCI packets, the software dynamically determines the length of the packet data by reading 2 bytes from the packet header. A buffer is then allocated to contain the entire packet, the size of which is calculated as the length of the packet body determined earlier plus the header length. WsfMsgAlloc then increments this again by sizeof(wsfMsg_t). This may cause an integer overflow that results in the buffer being significantly too small to contain the entire packet. This may cause a buffer overflow of up to 65 KB . This bug is trivial to exploit for a denial of service but can generally not be exploited further because the exploitable buffer is dynamically allocated.Show less

In intr_data_copy_cb of btif_hd.cc, there is a possible out of bounds read due to an integer overflow. This could lead to local information disclosure in the Bluetooth service with no additional execution privileges needed. User interaction is not needed for exploitation.Show less

In bta_hd_set_report_act of bta_hd_act.cc, there is a possible out-of-bounds read due to an integer overflow. This could lead to remote information disclosure in the Bluetooth service with no additional execution privileges needed. User interaction is not needed for exploitation.Show less

In xmlMemStrdupLoc of xmlmemory.c, there is a possible out-of-bounds write due to an integer overflow. This could lead to remote code execution in an unprivileged process with no additional execution privileges needed. User interaction is needed for exploitation.Show less

In IMSA_Recv_Thread and VT_IMCB_Thread of ImsaClient.cpp and VideoTelephony.c, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Show less

In SMF_ParseMetaEvent of eas_smf.c, there is a possible integer overflow. This could lead to remote denial of service due to resource exhaustion with no additional execution privileges needed. User interaction is needed for exploitation.Show less

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: avoid overflow in damon_feed_loop_next_input() damon_feed_loop_next_input() is inefficient and fragile to overflows. Specifically, 'score_goal_diff_bp' calculation can overflow when 'score' is high. The calculation is actually unnecessary at all because 'goal' is a constant of value 10,000. Calculation of 'compensation' is again fragile to overflow. Final calculation of return value for under-achiving case is again fragile to overflow when the current score is under-achieving the target. Add two corner cases handling at the beginning of the function to make the body easier to read, and rewrite the body of the function to avoid overflows and the unnecessary bp value calcuation.Show less

A vulnerability in the Modbus preprocessor of the Snort detection engine could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an integer overflow while processing Modbus traffic. An attacker could exploit this vulnerability by sending crafted Modbus traffic through an affected device. A successful exploit could allow the attacker to cause the Snort process to hang, causing traffic inspection to stop.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.Show less

In filterMask of SkEmbossMaskFilter.cpp, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.Show less

In Eclipse OpenJ9 versions up to 0.47, the JNI function GetStringUTFLength may return an incorrect value which has wrapped around. From 0.48 the value is correct but may be truncated to include a smaller number of characters.Show less

An issue was discovered in base/gsdevice.c in Artifex Ghostscript before 10.04.0. An integer overflow when parsing the filename format string (for the output filename) results in path truncation, and possible path traversal and code execution.Show less

WeeChat before 4.4.2 has an integer overflow and resultant buffer overflow at core/core-string.c when there are more than two billion items in a list. This affects string_free_split_shared , string_free_split, string_free_split_command, and string_free_split_tags.Show less
