Several security vulnerabilities have been discovered in isync, an IMAP and MailDir mailbox synchronizer. An malicious attacker who can control an IMAP server may exploit these flaws for remote code execution. . -------------------------------------------------------------------------Debian LTS Advisory DLA-3066-1
The package isync before version 1.4.4-1 is vulnerable to arbitrary code execution. . Arch Linux Security Advisory ASA-202112-5 ======================================== Severity: Medium Date : 2021-12-03 CVE-ID : CVE-2021-3657 CVE-2021-44143 Package : isync Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-2579 Summary ====== The package isync before version 1.4.4-1 is vulnerable to arbitrary code execution. Resolution ========= Upgrade to 1.4.4-1. # pacman -Syu "isync> =1.4.4-1" The problems have been fixed upstream in version 1.4.4. Workaround ========= None. Description ========== - CVE-2021-3657 (arbitrary code execution) A security issue was found in mbsync in isync versions before 1.4.4. Due to inadequate handling of extremely large (> =2GiB) IMAP literals, malicious or compromised IMAP servers, and hypothetically even external email senders, could cause several different buffer overflows, which could conceivably be exploited for remote code execution. - CVE-2021-44143 (arbitrary code execution) A security issue was found in mbsync in isync 1.4.0 before version 1.4.4. Due to an unchecked condition, a malicious or compromised IMAP server could use a crafted mail message that lacks headers (i.e., one that starts with an empty line) to provoke a heap overflow, which could conceivably be exploited for remote code execution. Impact ===== A remote attacker could execute arbitrary code on the mbsync client through crafted email messages.
