Improper Restriction of Operations within the Bounds of a Memory Buffer

An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function. libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memory lies after (or just crash) and then deliver that to the application as if it was actually downloaded.Show less

Flexense SyncBreeze Enterprise version 10.1.16 is vulnerable to a buffer overflow that can be exploited for arbitrary code execution. The flaw is triggered by providing a long input into the "Destination directory" field, either within an XML document or through use of passive mode.Show less

An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot be ruled out.Show less

The HTTP/2 experimental feature in Apache Traffic Server 5.3.x before 5.3.1 allows remote attackers to cause a denial of service (out-of-bounds access and daemon crash) or possibly execute arbitrary code via vectors related to the (1) frame_handlers array or (2) set_dynamic_table_size function.Show less

elfcomm.c in readelf in GNU Binutils 2.29 allows remote attackers to cause a denial of service (excessive memory allocation) or possibly have unspecified other impact via a crafted ELF file that triggers a "buffer overflow on fuzzed archive header," related to an uninitialized variable, an improper conditional jump, and the get_archive_member_name, process_archive_index_and_symbols, and setup_archive functions.Show less

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, miscalculates DW_FORM_ref_addr die refs in the case of a relocatable object file, which allows remote attackers to cause a denial of service (find_abstract_instance_name invalid memory read, segmentation fault, and application crash).Show less

The retr.c:fd_read_body() function is called when processing OK responses. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the allocated buffer.Show less

The http.c:skip_short_body() function is called in some circumstances, such as when processing redirects. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to skip the chunk in pieces of 512 bytes by using the MIN() macro, but ends up passing the negative chunk length to connect.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument.Show less

In F5 BIG-IP LTM, AAM, AFM, APM, ASM, Link Controller, PEM, PSM software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1, 11.4.0 to 11.5.4, when a virtual server uses the standard configuration of HTTP/2 or SPDY profile with Client SSL profile, and the client initiates a number of concurrent streams beyond the advertised limit can cause a disruption of service. Remote client initiating stream beyond the advertised limit can cause a disruption of service. The Traffic Management Microkernel (TMM) data plane is exposed to this issue; the control plane is not exposed.Show less

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, Websafe software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1, 11.4.0 to 11.5.4, 11.2.1, in some cases TMM may crash when processing TCP traffic. This vulnerability affects TMM via a virtual server configured with TCP profile. Traffic processing is disrupted while Traffic Management Microkernel (TMM) restarts. If the affected BIG-IP system is configured to be part of a device group, it will trigger a failover to the peer device.Show less

Use of an uninitialized value in Skia in Google Chrome prior to 61.0.3163.79 for Mac, Windows, and Linux, and 61.0.3163.81 for Android, allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page.Show less

Inappropriate use of partition alloc in PDFium in Google Chrome prior to 61.0.3163.79 for Linux, Windows, and Mac, and 61.0.3163.81 for Android, allowed a remote attacker to potentially exploit memory corruption via a crafted PDF file.Show less

An incorrect assumption about block structure in Blink in Google Chrome prior to 57.0.2987.133 for Mac, Windows, and Linux, and 57.0.2987.132 for Android, allowed a remote attacker to potentially exploit memory corruption via a crafted HTML page that triggers improper casting.Show less

A Heap-Based Buffer Overflow issue was discovered in Advantech WebOP. A maliciously crafted project file may be able to trigger a heap-based buffer overflow, which may crash the process and allow an attacker to execute arbitrary code.Show less

Multiple stack-based buffer overflows in TP-Link WR940N WiFi routers with hardware version 4 allow remote authenticated users to execute arbitrary code via the (1) ping_addr parameter to PingIframeRpm.htm or (2) dnsserver2 parameter to WanStaticIpV6CfgRpm.htm.Show less
