CVE-2020-27784 1 Linux 1 Linux Kernel 2024-11-21 N/A 5.5 MEDIUM
A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free().
CVE-2020-27675 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.7 MEDIUM 4.7 MEDIUM
An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5.
CVE-2020-27672 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-11-21 6.9 MEDIUM 7.0 HIGH
An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a host OS denial of service, achieve data corruption, or possibly gain privileges by exploiting a race condition that leads to a use-after-free involving 2MiB and 1GiB superpages.
CVE-2020-27418 1 Fedoraproject 1 Fedora Linux Kernel 2024-11-21 N/A 4.4 MEDIUM
A Use After Free vulnerability in Fedora Linux kernel 5.9.0-rc9 allows attackers to obatin sensitive information via vgacon_invert_region() function.
CVE-2020-27280 1 Deltaww 1 Ispsoft 2024-11-21 6.8 MEDIUM 7.8 HIGH
A use after free issue has been identified in the way ISPSoft(v3.12 and prior) processes project files, allowing an attacker to craft a special project file that may allow arbitrary code execution.
CVE-2020-27207 1 Zetetic 1 Sqlcipher 2024-11-21 5.0 MEDIUM 7.5 HIGH
Zetetic SQLCipher 4.x before 4.4.1 has a use-after-free, related to sqlcipher_codec_pragma and sqlite3Strlen30 in sqlite3.c. A remote denial of service attack can be performed. For example, a SQL injection can be used to execute the crafted SQL command sequence. After that, some unexpected RAM data is read.
CVE-2020-27067 1 Google 1 Android 2024-11-21 4.4 MEDIUM 6.4 MEDIUM
In the l2tp subsystem, there is a possible use after free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-152409173
CVE-2020-27066 1 Google 1 Android 2024-11-21 4.6 MEDIUM 6.7 MEDIUM
In xfrm6_tunnel_free_spi of net/ipv6/xfrm6_tunnel.c, there is a possible use after free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-168043318
CVE-2020-27044 1 Google 1 Android 2024-11-21 4.6 MEDIUM 7.8 HIGH
In restartWrite of Parcel.cpp, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-157066561
CVE-2020-27035 1 Google 1 Android 2024-11-21 2.1 LOW 5.5 MEDIUM
In priorLinearAllocation of C2AllocatorIon.cpp, there is a possible use-after-free due to improper locking. This could lead to local information disclosure in the media codec with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-152239213
CVE-2020-26972 1 Mozilla 1 Firefox 2024-11-21 7.5 HIGH 9.8 CRITICAL
The lifecycle of IPC Actors allows managed actors to outlive their manager actors; and the former must ensure that they are not attempting to use a dead actor they have a reference to. Such a check was omitted in WebGL, resulting in a use-after-free and a potentially exploitable crash. This vulnerability affects Firefox < 84.
CVE-2020-26960 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 9.3 HIGH 8.8 HIGH
If the Compact() method was called on an nsTArray, the array could have been reallocated without updating other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26959 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 6.8 MEDIUM 8.8 HIGH
During browser shutdown, reference decrementing could have occured on a previously freed object, resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26950 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 9.3 HIGH 8.8 HIGH
In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2.
CVE-2020-26539 1 Foxitsoftware 2 Foxit Reader, Phantompdf 2024-11-21 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Foxit Reader and PhantomPDF before 10.1. When there is a multiple interpretation error for /V (in the Additional Action and Field dictionaries), a use-after-free can occur with resultant remote code execution (or an information leak).
CVE-2020-26534 1 Foxitsoftware 2 Foxit Reader, Phantompdf 2024-11-21 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Foxit Reader and PhantomPDF before 10.1. There is an Opt object use-after-free related to Field::ClearItems and Field::DeleteOptions, during AcroForm JavaScript execution.
CVE-2020-25725 2 Fedoraproject, Xpdfreader 2 Fedora, Xpdf 2024-11-21 4.3 MEDIUM 5.0 MEDIUM
In Xpdf 4.02, SplashOutputDev::endType3Char(GfxState *state) SplashOutputDev.cc:3079 is trying to use the freed `t3GlyphStack->cache`, which causes an `heap-use-after-free` problem. The codes of a previous fix for nested Type 3 characters wasn't correctly handling the case where a Type 3 char referred to another char in the same Type 3 font.
