LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength. (CVE-2020-15503)
If a raw TCP socket is opened and connected to an endpoint that is fully configured with CURVE/ZAP, legitimate clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them (CVE-2020-15166).
LibEtPan through 1.9.4, as used in MailCore 2 through 0.6.3 and other products, has a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a meddler-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection". (CVE-2020-15953).
It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14 did not properly sanitize the search_path during logical replication. An authenticated attacker could use this flaw in an attack similar to CVE-2018-1058, in order to execute arbitrary SQL command in the context of the user used for replication. (CVE-2020-14349)
Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior (such as by causing excessive memory allocation). (CVE-2020-13757)
An Improper Output Neutralization for Logs flaw was found in Ansible when using the uri module, where sensitive data is exposed to content and json output. This flaw allows an attacker to access the logs or outputs of performed tasks to read keys used in playbooks from other users within the uri module. The highest threat from this vulnerability is to data confidentiality
ldebug.c in Lua 5.4.0 allows a negation overflow and segmentation fault in getlocal and setlocal, as demonstrated by getlocal(3,2^31). (CVE-2020-24370) References:
An issue was discovered in Squid before 4.13. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed
A heap buffer overflow in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to execute arbitrary code, aka GHSL-2020-080. (CVE-2020-12861) An out-of-bounds read in SANE Backends before 1.0.30 may allow a malicious
Cairo version 1.15.4 is vulnerable to a NULL pointer dereference related to the FT_Load_Glyph and FT_Render_Glyph resulting in an application crash. (CVE-2017-7475) References:
PuTTY 0.68 through 0.73 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client) (CVE-2020-14002).
A potential IMAP Man-in-the-Middle attack via a PREAUTH response (CVE-2020-14093). Mutt was ignoring an expired certificate and was proceeding with a connection (CVE-2020-14154).
In HylaFAX+ through 7.0.2, the faxsetup utility calls chown on files in user-owned directories. By winning a race, a local attacker could use this to escalate his privileges to root (CVE-2020-15396). HylaFAX+ through 7.0.2 has scripts that execute binaries from directories
This update is based on the upstream 5.7.19 kernel and fixes at least the following security issue: In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can
Fossil before 2.10.2, 2.11.x before 2.11.2, and 2.12.x before 2.12.1 allows remote authenticated users to execute arbitrary code. An attacker must have check-in privileges on the repository (CVE-2020-24614). The fossil package has been updated to version 2.10.2, containing fixes for
A maliciously crafted TAR archive containing symlink entries would install files anywhere in the user's home directory upon extraction (CVE-2020-24654). References: - https://bugs.mageia.org/show_bug.cgi?id=27214
By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed (CVE-2020-15664).
evolution-data-server (eds) through 3.36.3 has a STARTTLS buffering issue that affects SMTP and POP3. When a server sends a "begin TLS" response, eds reads additional data and evaluates it in a TLS context, aka "response injection". (CVE-2020-14928)
The handler for the XkbSetNames request does not validate the request length before accessing its contents (CVE-2020-14345). An integer underflow exists in the handler for the XIChangeHierarchy request (CVE-2020-14346).
There is an integer overflow and a double free vulnerability in the way LibX11 handles locales. The integer overflow is a necessary precursor to the double free (CVE-2020-14363). References:
