CVE-2019-20382 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2023-11-07 2.7 LOW 3.5 LOW
QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd.
CVE-2019-20367 4 Canonical, Debian, Freedesktop and 1 more 4 Ubuntu Linux, Debian Linux, Libbsd and 1 more 2023-11-07 6.4 MEDIUM 9.1 CRITICAL
nlist.c in libbsd before 0.10.0 has an out-of-bounds read during a comparison for a symbol name from the string table (strtab).
CVE-2019-1559 13 Canonical, Debian, F5 and 10 more 90 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 87 more 2023-11-07 4.3 MEDIUM 5.9 MEDIUM
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).
CVE-2019-1551 7 Canonical, Debian, Fedoraproject and 4 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
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).
CVE-2019-19956 7 Canonical, Debian, Fedoraproject and 4 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
xmlParseBalancedChunkMemoryRecover in parser.c in libxml2 before 2.9.10 has a memory leak related to newDoc->oldNs.
CVE-2019-19921 5 Canonical, Debian, Linuxfoundation and 2 more 5 Ubuntu Linux, Debian Linux, Runc and 2 more 2023-11-07 4.4 MEDIUM 7.0 HIGH
runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.)
CVE-2019-19911 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
There is a DoS vulnerability in Pillow before 6.2.2 caused by FpxImagePlugin.py calling the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.
CVE-2019-19906 8 Apache, Apple, Canonical and 5 more 20 Bookkeeper, Ipados, Iphone Os and 17 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.
CVE-2019-19844 2 Canonical, Djangoproject 2 Ubuntu Linux, Django 2023-11-07 5.0 MEDIUM 9.8 CRITICAL
Django before 1.11.27, 2.x before 2.2.9, and 3.x before 3.0.1 allows account takeover. A suitably crafted email address (that is equal to an existing user's email address after case transformation of Unicode characters) would allow an attacker to be sent a password reset token for the matched user account. (One mitigation in the new releases is to send password reset tokens only to the registered user email address.)
CVE-2019-19783 4 Canonical, Cyrus, Debian and 1 more 4 Ubuntu Linux, Imap, Debian Linux and 1 more 2023-11-07 3.5 LOW 6.5 MEDIUM
An issue was discovered in Cyrus IMAP before 2.5.15, 3.0.x before 3.0.13, and 3.1.x through 3.1.8. If sieve script uploading is allowed (3.x) or certain non-default sieve options are enabled (2.x), a user with a mail account on the service can use a sieve script containing a fileinto directive to create any mailbox with administrator privileges, because of folder mishandling in autosieve_createfolder() in imap/lmtp_sieve.c.
CVE-2019-19462 5 Canonical, Debian, Linux and 2 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2023-11-07 4.9 MEDIUM 5.5 MEDIUM
relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of service (such as relay blockage) by triggering a NULL alloc_percpu result.
CVE-2019-19344 4 Canonical, Opensuse, Samba and 1 more 7 Ubuntu Linux, Leap, Samba and 4 more 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer.
CVE-2019-19330 3 Canonical, Debian, Haproxy 3 Ubuntu Linux, Debian Linux, Haproxy 2023-11-07 7.5 HIGH 9.8 CRITICAL
The HTTP/2 implementation in HAProxy before 2.0.10 mishandles headers, as demonstrated by carriage return (CR, ASCII 0xd), line feed (LF, ASCII 0xa), and the zero character (NUL, ASCII 0x0), aka Intermediary Encapsulation Attacks.
CVE-2019-19246 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in str_lower_case_match in regexec.c.
CVE-2019-19221 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 2.1 LOW 5.5 MEDIUM
In Libarchive 3.4.0, archive_wstring_append_from_mbs in archive_string.c has an out-of-bounds read because of an incorrect mbrtowc or mbtowc call. For example, bsdtar crashes via a crafted archive.
CVE-2019-19126 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 2.1 LOW 3.3 LOW
On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
CVE-2019-19078 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-11-07 7.8 HIGH 7.5 HIGH
A memory leak in the ath10k_usb_hif_tx_sg() function in drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-b8d17e7d93d2.
CVE-2019-19074 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-11-07 7.8 HIGH 7.5 HIGH
A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.
CVE-2019-19072 4 Canonical, Fedoraproject, Linux and 1 more 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more 2023-11-07 4.9 MEDIUM 4.4 MEDIUM
A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.
CVE-2019-19071 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-11-07 7.8 HIGH 7.5 HIGH
A memory leak in the rsi_send_beacon() function in drivers/net/wireless/rsi/rsi_91x_mgmt.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering rsi_prepare_beacon() failures, aka CID-d563131ef23c.
