Firmware upgrade authentication bypass vulnerability was found in Dahua IPC-HDW4300S and some IP products. The vulnerability was caused by internal Debug function. This particular function was used for problem analysis and performance tuning during product development phase. It allowed the device to receive only specific data (one direction, no transmit) and therefore it was not involved in any instance of collecting user privacy data or allowing remote code execution.

Cross-site scripting (XSS) vulnerability in valider_xml.php in SPIP 3.1.2 and earlier allows remote attackers to inject arbitrary web script or HTML via the var_url parameter in a valider_xml action.

ghostscript: .libfile does not honor -dSAFER

Ghostscript before 9.21 might allow remote attackers to bypass the SAFER mode protection mechanism and consequently read arbitrary files via the use of the .libfile operator in a crafted postscript document.

Customer of Dahua IP camera or IP PTZ could submit relevant device information to receive a time limited temporary password from Dahua authorized dealer to reset the admin password. The algorithm used in this mechanism is potentially at risk of being compromised and subsequently utilized by attacker.

Multiple Cross-site scripting (XSS) vulnerabilities in Webmin before 1.850 allow remote attackers to inject arbitrary web script or HTML via the sec parameter to view_man.cgi, the referers parameter to change_referers.cgi, or the name parameter to save_user.cgi. NOTE: these issues were not fixed in 1.840.

libyara/re.c in the regexp module in YARA 3.5.0 allows remote attackers to cause a denial of service (stack consumption) via a crafted rule that is mishandled in the _yr_re_emit function.

The mp4ff_read_stsc function in common/mp4ff/mp4atom.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.7 allows remote attackers to cause a denial of service (large loop and CPU consumption) via a crafted mp4 file.

kernel: Incorrect overwrite check in __ip6_append_data()

The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel through 4.11.3 is too late in checking whether an overwrite of an skb data structure may occur, which allows local users to cause a denial of service (system crash) via crafted system calls.

The Bitcoin Proof-of-Work algorithm does not consider a certain attack methodology related to 80-byte block headers with a variety of initial 64-byte chunks followed by the same 16-byte chunk, multiple candidate root values ending with the same 4 bytes, and calculations involving sqrt numbers. This violates the security assumptions of (1) the choice of input, outside of the dedicated nonce area, fed into the Proof-of-Work function should not change its difficulty to evaluate and (2) every Proof-of-Work function execution should be independent. NOTE: a number of persons feel that this methodology is a benign mining optimization, not a vulnerability

oniguruma: Out-of-bounds stack write in onigenc_unicode_get_case_fold_codes_by_str() during regular expression compilation

An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds write in onigenc_unicode_get_case_fold_codes_by_str() occurs during regular expression compilation. Code point 0xFFFFFFFF is not properly handled in unicode_unfold_key(). A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of expand_case_fold_string() during the call to onigenc_unicode_get_case_fold_codes_by_str(), a typical stack buffer overflow.

The mp4ff_read_stco function in common/mp4ff/mp4atom.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.7 allows remote attackers to cause a denial of service (memory allocation error) via a crafted mp4 file.

qpdf: Infinite loop related to QPDFObjectHandle::parseInternal

libqpdf.a in QPDF 6.0.0 allows remote attackers to cause a denial of service (infinite recursion and stack consumption) via a crafted PDF document, related to QPDFObjectHandle::parseInternal, aka qpdf-infiniteloop2.

tcpdump: multiple overflow issues in protocol decoding

The ATM parser in tcpdump before 4.9.0 has a buffer overflow in print-atm.c:oam_print().

The iw_get_ui16be function in imagew-util.c:422:24 in libimageworsener.a in ImageWorsener 1.3.1 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image, related to imagew-jpeg.c.

tcpdump: multiple overflow issues in protocol decoding

The AH parser in tcpdump before 4.9.0 has a buffer overflow in print-ah.c:ah_print().
